Here you took response and using convertor you have generate the schema but what If we don't have response then how we are generating the schema. Are we creating manually by own.

[@RaghavPal]

Vaishali If you don't have a response, there are a few options: 1. Manual Creation: You can manually create the schema based on the API documentation or your knowledge of the expected response structure. This can be time-consuming and error-prone, especially for complex APIs. 2. Mock Responses: If possible, you can use a mock server or a similar tool to simulate the API responses. You can then generate the schema from these mock responses. 3. API Documentation: If the API follows specifications like OpenAPI (formerly Swagger), the schema might be available in the API documentation itself. Remember, the purpose of the schema is to validate the structure of the API response. So, it needs to accurately represent the expected response structure for your tests to be meaningful. If the schema is incorrect or incomplete, your tests might pass when they shouldn't, or fail when they shouldn't ..

Hi Raghav, Thank you for sharing your knowledge extensively in a calm understandable manner. I have been trying to use the POJO class inorder to generate json body to the Request Payload. But this looks tedious on multi level nested jsons, is there a way or library available, which can consider the json template and populate the data from either a csv file or xls . I tried to check online but couldnt get much info. Ex: consider below as the template, with $variables could directly be replaced { "names":["firstname": "$fname", "lastname":"$lname"], "personal":["Occup":{ "occ1":"$occvalue","occ2":"$occvalue2" }] } csv file has fname,lname,occvalue,occvalue2 etc Raghav,Pal,value2,value3 James,Jim,value4,value5

[@RaghavPal]

John Handling multi-level nested JSON structures and populating them with data from CSV or Excel files can be achieved using various tools and libraries. Let's explore some options: 1. Custom Scripting (Python, JavaScript, etc.): - You can write custom scripts to read data from a CSV file and dynamically replace placeholders in your JSON template. - For Python, you can use the `csv` module to read the CSV file and then format your JSON accordingly. - Similarly, in JavaScript, you can use libraries like `csv-parser` to parse CSV data and create the desired JSON structure. 2. Excel Add-ins (Microsoft Excel): - If you're working with Excel files, consider using Excel add-ins or macros. - You can create an Excel template with placeholders and use VBA (Visual Basic for Applications) macros to populate the data from a CSV file into the template. - This approach allows you to leverage Excel's built-in features for data manipulation. 3. Third-Party Libraries: - There are libraries available that simplify this process: - xlsx-populate (JavaScript): - This library allows you to read and modify Excel files (XLSX format) directly from JavaScript. - You can load an existing Excel template, replace placeholders, and save the modified file. - Plumsail Documents Connector (Power Automate): - Use the "Parse CSV" action from the Plumsail Documents connector to convert CSV data into an Excel table. - Then, populate the Excel table with the desired data. Remember to choose the approach that best fits your requirements and the tools you're comfortable with

You are welcome Manish

[@rohitkd90]

Hi Raghav - Sir I am getting the "Schema to use cannot be null" exception because the json file is getting auto-cleaned up / deleted from the target folder. How to fix this?

[@RaghavPal]

Rohit There are a few possible reasons why the JSON file might be getting deleted: * Eclipse's automatic build process might be cleaning up the target folder. * A plugin or feature in Eclipse might be configured to delete files in the target folder. * Your project's configuration or build script might be deleting the file. Step 1: Check Eclipse's build settings Check your Eclipse project's build settings to see if there's a configuration that's causing the file to be deleted. You can do this by: * Going to Project > Properties > Builders * Checking the "Clean" tab to see if there's a pattern that matches your JSON file * Checking the "Output Folder" tab to see if the target folder is being cleaned Step 2: Check for plugins or features Check if you have any plugins or features installed in Eclipse that might be causing the file deletion. You can do this by: * Going to Help > Eclipse Marketplace * Checking if you have any plugins installed that might be related to file cleanup or build processes Step 3: Check your project's configuration and build script Check your project's configuration files (e.g., pom.xml if you're using Maven) and build scripts to see if there's a configuration that's causing the file to be deleted. Step 4: Fix the issue Based on your findings, you can try one of the following solutions: * If Eclipse's build settings are causing the file deletion, update the settings to exclude the JSON file from the clean process. * If a plugin or feature is causing the file deletion, disable or uninstall the plugin. * If your project's configuration or build script is causing the file deletion, update the configuration to preserve the JSON file. Additional Tips: * Make sure the JSON file is in the correct location and is being copied to the target folder correctly. * Check if you're using a relative or absolute path to reference the JSON file in your Rest Assured tests. * Consider using a more robust way to manage your JSON schema files, such as storing them in a separate folder or using a schema management tool. -

Hey, thanks Franco

[@priyankav2890]

Hi sir , Can you suggest similar packages something for typescript projects

[@RaghavPal]

Priyanka Here are some popular libraries for JSON validation in TypeScript projects: 1. Ajv: A powerful JSON schema validator that supports TypeScript. It provides utility types like `JSONSchemaType` to simplify writing schemas ```bash npm install ajv ``` ```typescript import Ajv, { JSONSchemaType } from "ajv"; const ajv = new Ajv(); const schema: JSONSchemaType = { /* schema definition */ }; const validate = ajv.compile(schema); const valid = validate(data); ``` 2. ts-json-validator: This library allows you to define JSON schemas and TypeScript types in one place, ensuring they stay in sync ```bash npm install ts-json-validator ``` ```typescript import { createSchema as S, TsjsonParser } from "ts-json-validator"; const parser = new TsjsonParser( S({ type: "object", properties: { a: S({ type: "string" }), b: S({ type: "number" }), c: S({ type: "string", enum: ["B1", "B2"] as const }) }, required: ["a"] }) ); const valid = parser.parse(data); ``` 3. typeofweb/schema: A lightweight and extensible library for data validation with full TypeScript support ```bash npm install @typeofweb/schema ``` ```typescript import { object, string, number } from "@typeofweb/schema"; const schema = object({ a: string(), b: number().optional(), c: string().enum("B1", "B2").optional() }); const valid = schema.validate(data); ``` These libraries should help you ensure your API responses are correctly validated in your TypeScript projects -

[@prasadrangavali]

Hi Sir, I tried this but getting an error for "assureThat()". The method assertThat() is undefined for the type Response. please give the solution

[@RaghavPal]

Hi Prasad The `assureThat()` method is not a method of the `Response` class in Playwright. It is a method of the `expect` function, which is used to make assertions in Playwright tests. To assert something about a `Response` object, you can use the `expect` function with the `toEqual()` matcher. For example, the following code asserts that the status code of the `Response` object is 200: ``` const response = await page.request('example.com'); expect(response).toEqual({ status: 200, }); ``` The `assertThat()` method is a method of the `Assert` class in JUnit. If you are using JUnit to write your Playwright tests, you can use the `assertThat()` method to make assertions about `Response` objects. For example, the following code asserts that the status code of the `Response` object is 200: ``` import org.junit.Assert; public class MyTest { @Test public void testResponse() { const response = await page.request('example.com'); Assert.assertThat(response, Matchers.hasProperty("status", 200)); } } ``` I hope this helps

[@parveenparimi]

Hello Raghav, Can we use the same script for the console apps? I have to validate the Schema with Json. Please help

[@RaghavPal]

Praveen Yes, you can often reuse the same JSON schema validation script for both console apps and other environments, as long as it's written in a language that's compatible with your console app development framework. Here's a general approach: 1. Choose a JSON Schema Validation Library: - Select a library that supports your chosen programming language and offers robust validation features. Popular options include: - JavaScript: Ajv, tv4, jsonschema - Python: jsonschema - Java: json-schema-validator - C#: Newtonsoft.Json.Schema - And many more for various languages 2. Load the Schema and JSON Data: - Load the JSON schema from a file or string using the library's methods. - Load the JSON data you want to validate similarly. 3. Perform Validation: - Call the validation function provided by the library, passing the schema and data as arguments. - The function will typically return a result indicating whether the data is valid or not, along with any validation errors encountered. 4. Handle Results: - If validation succeeds, proceed with further processing of the JSON data. - If validation fails, handle the errors appropriately, such as: - Displaying error messages to the user - Logging errors for debugging - Terminating the application if necessary Console App Considerations: - Input/Output: Use appropriate console input/output methods to read the schema and data files, and display validation results. - Error Handling: Implement robust error handling to catch exceptions and provide meaningful feedback to the user. - Library Integration: Ensure the chosen validation library is compatible with your console app's development environment and dependencies. Example (Python): ```python import json from jsonschema import validate # Load schema and data with open("schema.json") as f: schema = json.load(f) with open("data.json") as f: instance = json.load(f) # Validate try: validate(instance, schema) print("JSON data is valid!") except jsonschema.ValidationError as e: print("JSON data is invalid:", e) ``` Key Points: - Reusability: JSON schema validation scripts are often reusable across different environments. - Library Choice: Select a library that aligns with your programming language and requirements. - Error Handling: Implement robust error handling for user-friendly validation feedback.

im getting "Schema to use cannot be null" error, how to resolve it

[@RaghavPal]

Ashwini Here’s how to resolve the "Schema to use cannot be null" error in Rest Assured: 1. Check Your Schema File Path: Ensure the path to your JSON/XML schema file is correct and exists 2. Use `File` Object for Schema: Load the schema using a `File` object: ```java File schema = new File("path/to/your/schema.json"); ``` 3. Add Schema Validation: Use `RestAssured`'s `matchesJsonSchema` or `matchesJsonSchemaInClasspath` method: ```java given() .get("your/api/endpoint") .then() .assertThat() .body(matchesJsonSchema(schema)); ``` 4. Verify Dependencies: Add the correct schema validation library to your `pom.xml`: ```xml io.rest-assured json-schema-validator latest_version ``` 5. Fix Null Schema: Double-check if the schema file is actually being loaded. If not, debug the path issue. This should fix your error .

[@BhuvaneswariSarath-h4d]

Hi Raghav, for POST Request I need to pass some 30 line of Request body. How to handle that .

[@RaghavPal]

Bhuvaneswari There are two ways to handle a 30-line request body in a POST request using Rest Assured: 1. *Use a string:* You can simply pass the request body as a string to the `body()` method. For example: ```java String requestBody = """ { "name": "John Doe", "age": 30, "occupation": "Software Engineer", ... } """; given() .contentType(ContentType.JSON) .body(requestBody) .when() .post("/users"); ``` 2. *Use a file:* If the request body is very large or complex, you can store it in a file and then pass the file to the `body()` method. For example: ```java File requestBodyFile = new File("request_body.json"); given() .contentType(ContentType.JSON) .body(requestBodyFile) .when() .post("/users"); ``` Which method you choose depends on your specific needs. If the request body is relatively small and simple, then you can simply pass it as a string. If the request body is very large or complex, then you should store it in a file and then pass the file to the `body()` method. Here are some additional tips for handling a 30-line request body in a POST request using Rest Assured: * Use a JSON parser to parse the request body into a JSON object. This can be useful for validating the request body or for extracting data from the request body. * Use a string builder to build the request body. This can be useful for creating a complex request body from multiple parts. * Use a file reader to read the request body from a file. This can be useful for handling very large request bodies. I hope this helps

[@RaghavPal]

Andy The error you're encountering suggests that the io.restassured.module.jsv package is not found. This package is part of the Rest Assured library, specifically for JSON schema validation One possible reason for this issue is that you might be missing the necessary dependency in your project's pom.xml file. You need to include the following dependency to use JSON schema validation: com.jayway.restassured json-schema-validator 2.1.0 Make sure to add this dependency to your project's pom.xml file and try importing the JSONSchemaValidator class again Another possible reason could be that you're using an older version of Rest Assured that doesn't have the io.restassured.module.jsv package. You can try updating your Rest Assured version to the latest one -

Sir can we do contract testing using Rest-assured?

[@RaghavPal]

Hi Ali No, Rest-assured is a Java-based library for testing RESTful APIs, but it is not designed specifically for contract testing. Contract testing involves verifying that two communicating systems, such as a client and a server, adhere to an agreed-upon interface or contract. It ensures that changes made to one system do not break the other system's functionality. Rest-assured can be used to write tests that validate the functionality of RESTful APIs, which can be part of the overall contract testing process.

[@AliRaza-nl6tf]

@@RaghavPal Sir do we have any open source tool for contract testing other than PACT?

[@RaghavPal]

Yes, there are several open source tools available for contract testing, in addition to PACT. Here are a few options you can consider: Spring Cloud Contract: Spring Cloud Contract is an open source framework that allows you to write consumer-driven contract tests in Spring-based applications. It supports several messaging protocols and can generate stubs and tests for both the consumer and provider sides of the contract. Spring Cloud Contract also integrates with popular testing frameworks like JUnit and TestNG. Hoverfly: Hoverfly is an open source API simulation and testing tool that can be used for contract testing. It allows you to simulate API responses and generate contract tests automatically. It supports several languages and protocols and can be integrated with popular testing frameworks like JUnit and TestNG. Pactum: Pactum is a lightweight, open source contract testing library that can be used to test RESTful APIs. It supports both JSON and XML request and response payloads and can generate stubs and tests automatically. Pactum also integrates with popular testing frameworks like Mocha and Jest. Karate DSL: Karate DSL is an open source testing framework that can be used for contract testing. It supports both HTTP and HTTPS protocols and allows you to write tests in a simplified, English-like syntax. Karate DSL also provides built-in support for data-driven testing and can be integrated with popular CI/CD tools like Jenkins. These are just a few examples of open source contract testing tools available. The best tool for your needs depends on your specific requirements and preferences.

i am getting an error its showing schema can not be null

[@RaghavPal]

Jaimin While I don't have access to the specific query responses and ratings you mentioned, I can provide general guidance and potential solutions based on common causes of this error: Understanding the Error: - This error usually indicates that Rest Assured is unable to locate or access the JSON schema file you're trying to use for validation. - Double-check that you've provided the correct file path or schema object to the relevant validation methods. Troubleshooting Steps: 1. Verify Schema Path: - Ensure the path you're specifying in your code points to the exact location of the schema file relative to your project directory. - If it's an external URL, confirm that the URL is reachable and doesn't require authentication. - Consider using absolute paths or classpath-relative paths for clarity. 2. Inspect Schema Content: - Make sure the schema file is valid JSON and doesn't contain syntax errors. Use JSON validators or linters to check for issues. - Verify that the schema structure aligns with the expected response from the API endpoint you're testing. 3. Check Schema Object Construction: - If you're building the schema dynamically, ensure you're using the correct methods and providing valid data according to Rest Assured's schema API. - Double-check for typos or incorrect values in your schema construction code. 4. Handle Null Schemas: - If the schema might be null in certain scenarios, implement logic to handle that gracefully. You could conditionally apply validation or provide a default behavior. 5. Consider Other Possibilities: - If the above steps don't resolve the issue, provide more context about your test code, schema location, and the specific method you're using for validation. - Check for compatibility issues between your Rest Assured version and any external libraries you're using for schema handling. Code Example (Basic Case): ```java import static io.restassured.module.jsonschema.JsonSchemaValidator.*; // Assuming you have a valid JSON schema file named "schema.json" in your project's resources directory String schemaPath = "classpath:schema.json"; given() ./* other request setup */ .when() .get(/* your API endpoint */) .then() .assertThat() .body(matchesJsonSchemaInClasspath(schemaPath)); ``` I hope this helps..

[@RaghavPal]

Hi Mahesh Here is the code to automate the challenge on Rest Assured: ``` import org.hamcrest.Matchers; import org.testng.annotations.Test; public class RestAssuredChallengeTest { @Test public void testUnauthorizedAccess() { // Get the session ID from the first user String sessionId = getSessionIdFromFirstUser(); // Try to access the resource with the session ID from the first user given() .cookie("sessionId", sessionId) .when() .get("/resource") .then() .statusCode(401); } private String getSessionIdFromFirstUser() { // Get the response from the first user Response response = given() .when() .get("/resource"); // Get the session ID from the cookies return response.cookies().get("sessionId"); } } ``` This code will first get the session ID from the first user. Then, it will try to access the resource with the session ID from the first user. Finally, it will check the status code of the response, which should be 401. To run this code, you will need to have Rest Assured installed. You can install Rest Assured using the following command: ``` mvn install org.rest-assured:rest-assured:latest ``` Once you have installed Rest Assured, you can run the code by running the following command: ``` mvn test ``` This will run the test and print the results to the console.

java.lang.IllegalArgumentException: Schema to use cannot be null getting this error

[@RaghavPal]

Afwan The error message you're encountering-"java.lang.IllegalArgumentException: Schema to use cannot be null"-indicates that the schema you're trying to use for JSON validation is null. Let's troubleshoot this issue: 1. Check Your Schema File: - Ensure that the JSON schema file you're using for validation exists and is accessible. - Verify that the file path is correct and that the schema content is valid. 2. Use Correct Schema Path: - When using `matchesJsonSchemaInClasspath`, make sure the schema file is in the correct location relative to your classpath. - The schema file should be in the `src/test/resources` directory (or a subdirectory within it). - Example: ```java .body(matchesJsonSchemaInClasspath("schemas/my-schema.json")) ``` 3. Check for Null Values: - If you're dynamically loading the schema content, ensure that it's not null. - Double-check any logic that sets the schema content. 4. Verify Dependencies: - Make sure you have the necessary dependencies for JSON schema validation. - Ensure that you're using the correct version of the library (e.g., `io.rest-assured:json-schema-validator`). 5. Test with a Simple Schema: - Temporarily use a simple schema (even an empty one) to see if the issue persists. - If it works with a basic schema, gradually add complexity to your schema. 6. Inspect Your Test Code: - Review your test code to ensure that you're correctly invoking the schema validation. - Check if there are any null assignments or missing steps. 7. Update Dependencies: - If you're using an older version of Rest Assured or its dependencies, consider updating to the latest version. Remember to adapt these steps based on your specific project structure and requirements .

java.lang.IllegalArgumentException: Schema to use cannot be null I'm getting this error ,can anyone please give me the answer to correct it

[@RaghavPal]

Joseph Let's break down the problem step by step. Problem: The error indicates that the schema to use is null, which is not allowed. Possible Causes: 1. Missing or invalid schema configuration: Rest Assured uses a schema to validate the response. If the schema is not provided or is invalid, it will throw this error. 2. Incorrect usage of `given()` or `expect()` methods: The `given()` and `expect()` methods in Rest Assured are used to specify the request and response specifications, respectively. If these methods are not used correctly, it can lead to this error. Step-by-Step Solution: 1. Check your Rest Assured configuration: Make sure you have properly configured Rest Assured to use a schema. You can do this by specifying the schema using the `schema` method or by providing a JSON schema file. Example: ```java RestAssured.config = RestAssured.config().schemaConfig(new SchemaConfig().with().mimeTypes("application/json", "json")); ``` 2. Verify your request specification: Check that you are using the `given()` method correctly to specify the request details. Example: ```java given() .header("Content-Type", "application/json") .body(requestBody) .when() .post("/api endpoint"); ``` 3. Verify your response specification: Check that you are using the `expect()` method correctly to specify the response details. Example: ```java expect() .statusCode(200) .body("key", equalTo("value")); ``` 4. Check for null values: Ensure that you are not passing null values to the `given()` or `expect()` methods. Example: ```java // Avoid this: given().body(null); // Instead, use an empty string or a valid request body: given().body(""); ``` 5. Review your JSON schema file (if using): If you are using a JSON schema file, ensure that it is valid and correctly configured. Example: ```java // schema.json file: { "$schema": "json-schema.org/draft-04/schema#", "type": "object", "properties": { "key": {"type": "string"} } } ``` By following these steps, you should be able to identify and fix the issue -
