Software Testing Tutorial #37 - State Transition Testing Technique

[@manoj_mafiosi]

**Notes: State Transition Testing Technique - Software Testing Tutorial #37** **Introduction:** - State Transition Testing, a black-box testing technique useful for systems with states and state changes, resembling a finite state machine. **Understanding State Transition Testing:** - State Transition Testing involves defining an application/module in terms of states and transitions. - Similar to a workflow diagram, it outlines various states and how transitions occur between them. - Review other black-box test design techniques like Equivalence Partitioning, Boundary Value Analysis, and Decision Table Testing before diving into State Transition Testing. **Example: Banking Website Scenario:** - Example: Entering an incorrect username and password three times results in an account lock, requiring a password reset. **Defining States:** 1. Start State 2. Waiting for Username and Password 3. First Attempt 4. Second Attempt 5. Third Attempt 6. Access to Account 7. Account Blocked **Defining Transitions:** - Clicking on Login Button: Transition from Start State to Waiting for Username and Password. - Correct Username and Password (Any Attempt): Transition to Access to Account. - Incorrect Username and Password (First and Second Attempt): No change in state. - Incorrect Username and Password (Third Attempt): Transition to Account Blocked. **Creating Test Cases:** - Test Case 1: Enter incorrect credentials in the first attempt, then correct credentials. Expected result: Access to Account. - Test Case 2: Enter incorrect credentials three times. Expected result: Account Blocked. **Four Key Elements in State Transition Testing:** - **States:** Different conditions or phases the application can be in. - **Transitions:** How the application moves between states. - **Events:** Trigger transitions, e.g., clicking a button. - **Actions:** Consequences or responses to events, e.g., displaying an error message. **Conclusion:** - State Transition Testing defines an application's behavior in various states and transitions. - It ensures software responds correctly to different scenarios.

Thank you so much! After dozens of videos and lots of reading it is at clear at last!

[@amahlendongeni9895]

It was so easy for me to understand after this explanation, thank you.

[@tanwirh2213]

you forgot a key element in this video: how to actually convert each unique transition flow into a test case

[@joshatapagra9086]

I really hope to gain a remote software testing job after this tutorial. Thank you so much for your lessons.

[@softwaretestingmentor]

Good luck! Keep watching for more videos and tutorials.

[@seemasahu1787]

Thank u sir. You have made easy this topic for me, because before some time I was very confuse about that topic.

[@NatashasVocals]

you are the best so far thank you

[@Vasterize]

Now i get it! Thank you for greate explanation!🤗

[@2yoo5]

Thank you for explaining

You are so welcome! Keep watching for more videos and tutorials.

[@anamikatanwar1954]

Perfectly explained..good job sir

[@mangeshmehare9669]

Nice explained.

[@softwaretestingmentor]

Thank you 🙂 Keep watching for more videos!

[@samiullahkhan3039]

nice watched in 2x

[@Ogk8036]

Thank you.

[@softwaretestingmentor]

You're welcome. Keep watching for more videos!

[@iamstilllearningthekoreanl1228]

It's similar to decision making table technique?

[@gyanbaimishra9466]

Thank you sir

[@iamstilllearningthekoreanl1228]

If the customer can enter his username and password for 100th times but on 111th attempt application should not be allowed and give some error. How can we test this case? Sir

[@burnoctane5634]

Thank you sir ❤️

[@softwaretestingmentor]

Most welcome. Keep watching for more videos!

[@amitmal7596]

but, this wat isnt any software a basically state transitioning program?

[@user-pu5vk9jq3l]

In this example of state transition testing. It looks like a system flowchart. That you need to input process output. Is it the same or they're different? Thanks

wow
