One of the best video about System Testing. Simply the best

[@darlenematthews6353]

Thanks for this. Your great! I just wanted to add this for newbies.... *White box testing involves knowledge of code and internal works of software. *Black box testing involves performance and functionality (external); no use of code and no internal knowledge. Used by entry level testers. *Grey Box testing is the combination of both.

[@kishores1020]

GREAT VIDEO! But considering integration testing only a part of white box testing is wrong.It is also done in black box testing. I understand you need stubs and drivers for top down and bottom up approach but categorizing it only under white box is wrong.

[@QA1]

Hi Kishore, I do say "majorly" at 3:18. The main difference between white box testing and black box testing is whether we test with the source code or the executable. Many thanks for your subscription.

[@shehana4172]

Thank you this was helpful. I have Question, Is unit testing necessary? Or I can do other tests without it ?

[@QA1]

You are welcome to the Software and Testing Training channel. Unit testing is necessary. If there is defect leakage due to insufficient or no unit testing, later levels require more effort to find the leaked defect(s).

[@AtulMalokar]

nice job sir

[@Raouf4eva]

Hello sir I have a question. When writing a test plan do you specify what type of testing will be done in the back end? And is database testing required in the test plan? Where is the documentation regarding back end testing? Such as what to test and how to test queries. Can you please assist me with this question. I need to know if backend/database testing is listed in the test plan. Thank you!

[@QA1]

Thank you for your question. Yes, the types of testing (including db/ backend testing) are mentioned in the Test Scope section of the test plan. Whether database testing is required or not depends on the project requirements. For example, if new database objects (new tables, indexes, stored procedures) are released, then database testing should be done. You can see an example of test strategy/ test plan in my video at kzbin.info/www/bejne/rJ6YnHqva7qFoK8

[@chandrakantdhutadmal9810]

Hi Inder. You have good videos on Software Testing. I have a question regarding Sanity Testing and Installation Testing. You have mentioned in your video that Sanity Testing is done to check if you can take the system for further testing or not. But how can we do Sanity testing without Installing the software or system. So, is it not that Installation testing is the first testing to be done before sanity testing. ? Also, what is the difference between sanity testing and smoke testing ?

[@QA1]

+Chandrakant Dhutadmal Hi Chandrakant, you are right, sanity testing can be done only after the build is installed or deployed. Still, we can do sanity testing (to see if the major functionality is working) first. If the sanity test passes, then only invest the time to do the detailed installation testing (check that all options work, the install works on each supported environment etc.). Smoke testing is the older term. Sanity testing is the current term. Thank you for your questions.

[@shashikanthapadmala4427]

this video is very helpful .Nice explanation sir and thank you

[@QA1]

shashikantha padmala Thank you so much.

[@TheAnjaligoel]

Thank you so much for all your wonderful videos. Can you please share your view on difference between System testing and End to end testing?

[@QA1]

Anjali G Thank you for following this channel. My view is that different people may have different perceptions of testing terms. Hence, it is valuable to clarify it if a client or a manager mentions a testing term. IMO, end-to-end testing is included in system testing. In end to end testing, we test the entire user workflows (to accomplish high-level tasks) from beginning to end. For example a workflow in a flight reservation system may be, log in, search flight, select a flight, enter customer and financial information, view itinerary and log out. Does this clarify it?

[@TheAnjaligoel]

Software and Testing Training I thank you for your prompt response. Would it be apt to say that E2E testing is Black box testing whereas System Testing is combination of both White box and black box testing? Also, I'd like to understand if E2E testing deals with testing the functionality of a specific module or the whole system altogether? For example: facebook... If I login , put a status and logout, would it be E2E testing? Second time, if I log in and like and comment on friend's post, would it be E2E testing for another module? I am actually kind of confused, if we test all the functionalities and modules altogether or in pieces in E2E testing. System testing and E2E testing have always sounded so similar to me. Please excuse me for such big text!

[@QA1]

Anjali G Here is what I think: [Question]: Would it be apt to say that E2E testing is Black box testing whereas System Testing is combination of both White box and black box testing? Not really. I understand the testing levels as unit testing, integration testing, system testing and acceptance testing. White box or black box testing is a different categorization. Still, white box testing is more suited in the unit testing and integration testing levels. I think that black box tests are more suited to the system testing level. [Question]: Also, I'd like to understand if E2E testing deals with testing the functionality of a specific module or the whole system altogether? For example: facebook... If I login , put a status and logout, would it be E2E testing? Second time, if I log in and like and comment on friend's post, would it be E2E testing for another module? It does not matter if it tests a single module or the entire system (and inter-connected systems). It is based on the user workflows. Your examples (update a status and like a post) are perhaps too short to be really typical workflows. I don't use Facebook much but I imagine that a typical user would do a number of tasks like log in, check the home page, check other status updates, view images or text, like or comment, reply to messages,.., log out.

[@TheAnjaligoel]

Software and Testing Training Thank you so much!

[@donesy125]

Integration Testing can be Black Box Testing, it is not only White Box

[@Raouf4eva]

Hello sir, I wanted to ask you a question.. I was wondering how do you set up a test environment? and how do you start testing? Will it be with compiling the developers code or will there be a link provided to you when working on a project? Can you please help me with this topic. That you!!!!

[@QA1]

+raouf dou Different organizations have different roles responsible to set up the test environment. It could be the developers, operations or QA who set it up. If it is QA, they may get release notes/ installation instructions from the developer on how to set up the test environment. It is common to get a build (which needs to be installed) or a link (where the system has been installed). QA represents the user so it is uncommon for QA to have to compile the developers code first. If applicable, installation testing is done. Then sanity testing. This is followed by system testing. Thank you for your question.

[@nagarajaballal.c2300]

Hi,video is usefull.But i have one doubt,is UNIT,INTEGRATION testing done by developers and System Testing is done by testers?

[@QA1]

***** That is correct. Thank you for your question.

[@rufimn]

As per your video, Requirement Specifications can be in the form of Functional Requirements or User stories, however you are missing that Requirement Specifications contain both Functional and NON-FUNCTIONAL REQUIREMENTS, isn''t it? In iterative incremental, i.e Agile models, System testing of partially developed system is done after every sprint, until we complete all the sprints and a full system is produced??

[@QA1]

That is correct.

[@rufimn]

Hello, In Unit testing all the modules have been checked to make sure all units are working properly as per requirements. Integration testing is then performed to make sure all the units have been working together and a complete system is formed How then in System Testing we find a defect , when at the lowest 2 levels(Component and Integration Testing) everything was tested and working perfectly??

[@QA1]

Hello! Actually, in Integration testing, we test the integration between the units. In System testing, the system is tested as a whole. In the System testing level, we do sanity testing, installation testing, functional testing off system design requirements, extra-functional testing like performance testing, security testing, usability testing etc., regression testing and testing the integration with other systems.

[@rufimn]

Agreed on the types of testing we performed at System Testing Level. Why we found defects during System Testing when we build everything as per user requirements and everything was checked in unit testing and unit integration testing??

[@QA1]

OK. Firstly, the requirements are of two types - stated (explicit) and implied (implicit). Even the stated requirements can have defects. Therefore, any testing based just off stated requirements can be insufficient or incorrect. Secondly, everything CANNOT tested in unit testing and integration testing e.g. system performance or integration with other systems can only be tested during System Testing, which is only possible when the complete system is available.

[@rufimn]

Agreed that there might be some misunderstanding in communicating the requirements to the system analyst which in turn will have the requirements which the customer didn't want. (Incorrect Requirements). Unit/Modules are built as per those incorrect requirements and acceptance testing is done at unit level to accept the module . We then move to Integration testing and all modules are integrated to form a System and a correction check is done at that level as well. Now when system testing is done, there should NOT be any defects as system is built as per the requirements , some of which are "INCORRECT". Only now, after the System Testing, when the Acceptance testing is done(which might be a demo to the customer)the customer finds that some of the requirements were not understood properly and system has some faults. But we didn't find those faults in System Testing , thus the defects in system testing is still a mystery for me ;)

[@Raouf4eva]

hello sir, quick question.. What is a software release? (new release) is version number different. Is testing different with it, such as regression with a new release. Sorry about all the stupid questions.. Thank you!

[@QA1]

Software is the set of instructions for a system. When we change the software (whether compiled or as source code, as applicable), it is a new software release. Before the software is released, it should be tested. This testing should include new requirement testing and regression testing. The latter should be based on the impact of all the changes done to the software in this release. Thank you for your questions.

[@Raouf4eva]

What do you mean when you say compiled or a source Code change? So when a code changes then it will be a new release ? Why type of code change does that depend on? So when new code is added to the previous code then it's just another version number? And if the previous code gets changed then it's a new release? Does that apply to the backend also? And what did you mean when you say compiled? If you could please explain this to me. Thank you so much!!

[@QA1]

The software in the system is written using one or more programming languages. Some programming languages like C++ or Java require compilation before the program can be run. Others like JavaScript are interpreted so only the program source code is required to run. Hope this clarifies it.

[@TheNemolala]

Thank you , Perfect Explain to System Testing , I have one Question Sir : How to do UAT by testers in Real World ...What is the difference between System Testing And UAT ?

[@QA1]

Hi Tasneem, one difference between System Testing and UAT is that System Testing level has more detailed testing than UAT. Also, System Testing can include non-functional types of testing like performance testing, usability testing, security testing. The focus in UAT is testing for business requirements done by end-users (or testers working on behalf of end-users) to decide whether to accept the system or not. I have also explained the differences in the last part of my V-model video at kzbin.info/www/bejne/oGfVqayIrKqXjLc

[@Sparshgr8]

Thanks for the video again, I have a doubt, Is there any difference between Unit testing and module testing ?

[@QA1]

Sparsh Jain It depends on how we define module testing. In unit testing, we test a function or a class or a package. If a small unit passes the test, we can test its parent unit. Module testing seems a type of unit testing, but dealing with a larger unit. Thank you for your question.

[@Sparshgr8]

Software and Testing Training Thanks for the answer :)

[@Raouf4eva]

hello sir, what is a stub and driver?? I know its used during integration testing when all modules are not ready so I was wondering how is a stub and driver created? not sure if you can please answer this.. How and who's it created by.

[@QA1]

A stub is a function that can be temporarily used in place of the real function, that is under development. A driver function calls other functions to complete any work. Developers and Automation Engineers have been creating stubs and drivers for a long time. A stub mocks the function output. A driver calls functions implemented in various classes.

Hello sir, I have to ask you for a huge favor. I was wondering how do you write a test case for database testing? Could you please provide me a example? SQL server is the database and the testing would be the new Columns/updated data. How could I write a test case for that? If you could please guide me that would be amazing!! Thank you so much!!!!!

[@QA1]

Here are some examples for database testing for new columns/updated data 1) Validation of the length, data type, allow null and names of columns per existing database design and new requirement 2) Whether primary key and foreign keys are valid 3) Whether the data in the respective columns maps to the data shown in the user interface correctly (insert, update and delete operations)

[@Raouf4eva]

Hello sir I have 2 questions. 1st one is that how would you test config files? The 2nd question is that how would you test XML ? Thank you sir!

[@QA1]

Basic tests should include testing with missing config file, each test data item is used or not, default values, minimal configuration and maximum configuration. You can see my test ideas tutorial to learn how to design more tests. I have explained configuration data in my Test Data tutorial at kzbin.info/www/bejne/jn-9Y4OjZ7l0i9U

[@GovindGuptaWittyWriter]

Sir, Can you please give me live example (practical) face to face.

[@Raouf4eva]

how do you do installation testing?

[@QA1]

+raouf dou Installation testing involves testing the installation process per the install instructions provided by the developer. The installation process must work on supported system configurations. Depending on the requirements, installation testing covers full install, re-install/ repair, side-by-side install, update and uninstall processes.

[@MrPmandizzle]

can someone help me with this question? Explain how system testing could incorporate testing for users who require assistive technology?

[@QA1]

In system testing, you should test the software requirements and system specifications related to accessibility. The relevant software requirements would be extra-functional requirements intended to make the system usable by users who have some type of disability. In system testing, you can pretend to be a user with a specific disability and test if you can use the system with the supported assistive technologies. Here are a couple of examples: 1 - The system should be accessible by a user depending on text-to-speech conversion. The menu item names, labels and text should be self-explanatory and allow the user to understand the UI and the content. Images should have alternate descriptions. 2 - The system should be accessible by a user who needs a display with large font-size, high-contrast, large images etc. Thank you for your question.

[@niharikamehta]

sanity testing and smoke testing, what is the difference?

[@QA1]

There is a big debate ongoing since long on the difference between sanity testing and smoke testing. Would not like to confuse anyone more by adding more differences :) IMO, in software system testing, we have value for sanity testing. It is the initial testing on receiving a new build. It covers build install/ deployment, starting the system and testing if the major features of the system work with common workflows. E.g. it is possible to install the new web pages, components and refresh the database. Then, it is possible to start the web site, login as a user successfully and perform the common operations like search products, place an order, check out and see the orders report. Thanks for your question, Niharika.

[@Raouf4eva]

Hello sir, how can you know the version number, if the Release number is: 12.04.04 and the build number is: 1.0 ?? How can you tell what the version number will be? Thank you sir very much for all your assistance. .......... And I was wondering how can you do data mapping test? Say if there is an update in the data mapping how can you test that?

[@QA1]

It is not possible to predict the version number from the release number and build number. It depends on the naming system chosen by the organization. In my knowledge, version is the primary data to distinguish the software from its previous editions. Release number, build number and service pack number are secondary.

[@yaswanthchallagunda3024]

I too had a doubt on it...it was asked in one of my project interview...what is difference between smoke and sanity...any one

[@Abhishekyadav-xd2ib]

Smoke testing - testing the basic and critical functions of software. By giving positive value only.. we do smoke testing to check weather software is testable or not. Because software should work atleast for positive value, if rhere will be any blocker or critical issue so we can send that report to D.E, it will save time.

[@Abhishekyadav-xd2ib]

Sanity testing - testing the impacted region due to making Change in dependent part. We do sanity testing when there is change in part, so we check dependent part, weather this change is working correctly there or not.

[@rakeshchary4235]

it's not sanity test but it's smoke test you should call.
