Today, we're going to discuss Sanity Testing. Can anyone explain what they think it involves?

Student 1
Student 1

Isn’t it about quickly checking if a fix works or not?

Teacher
Teacher

Exactly! Sanity Testing is a quick check to ensure that a recent bug fix or functionality works as expected. Think of it as a sanity check for the software.

Student 2
Student 2

So, it’s only about one specific issue?

Teacher
Teacher

Yes! It's focused rather than comprehensive. If a bug is fixed in the cart, we test that specific flow without looking at unrelated areas.

Student 3
Student 3

Why is it important to do this?

Teacher
Teacher

Great question! It helps us ensure that fixes are valid before we spend time on more extensive testing. It’s like a preliminary assessment.

Teacher

In short, Sanity Testing is essential for maintaining software quality. Remember: It's all about checking that the specific function remains functional after changes.

Now that we’ve covered the basics, what do you think would be included in a typical Sanity Test?

Student 4
Student 4

Would it involve just rerunning the test cases associated with the bug?

Teacher
Teacher

Yes! Those specific test cases are executed again to validate the fix. Who can think of an example?

Student 1
Student 1

If there was a bug in the checkout process, I imagine we'd only test that instead of the whole system.

Teacher
Teacher

Exactly! Sanity Tests save time by narrowing down the focus to affected areas, allowing us to quickly confirm functionality.

Student 2
Student 2

Would this be done before every deeper testing phase?

Teacher
Teacher

Yes! It serves as a checkpoint. If Sanity Tests pass, it indicates that we can cautiously proceed with more detailed testing.

To summarize, always remember that Sanity Testing is your initial line of defense against regressions in modified functionalities.

Sanity Testing vs. Smoke Testing

Now, let’s compare Sanity Testing and Smoke Testing. Can someone distinguish them for us?

Student 3
Student 3

I think Smoke Testing checks general stability, while Sanity Testing is more focused?

Teacher
Teacher

Correct! Smoke Testing checks basic functionalities, ensuring critical systems work, like login and homepage load. Whereas Sanity Testing digs into recent changes only.

Student 4
Student 4

So, we use both, but at different stages?

Teacher
Teacher

Precisely! Smoke Testing is typically done after a new build, while Sanity Testing follows specific bug fixes. Anyone want to offer an example to illustrate this?

Student 1
Student 1

If we deployed a new version, Smoke Testing checks the app starts up. If a specific bug was fixed afterward, we’d do Sanity Testing on that fix.

Teacher
Teacher

Exactly! This comparison helps clarify the purpose of both, supporting the overall testing strategy. Great discussion, everyone!

Introduction & Overview

Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.

Quick Overview

Sanity Testing is a brief test conducted to ensure that specific functionalities behave as expected after changes are made.

Standard

Sanity Testing is focused testing utilized to validate individual functionalities or bug fixes. It checks whether a particular function works before further testing proceeds, typically following bug fixes or minor changes.

Detailed

Sanity Testing

Sanity Testing is a critical aspect of software testing that is performed after changes have been made to the codebase, specifically targeting recent bug fixes or functionality additions. Its primary purpose is to confirm that the specified functionalities work as intended, thereby ensuring a stable foundation for additional tests.

Key Points

  1. Purpose: Sanity Testing aims to validate that a particular bug has been fixed or a specific function operates correctly.
  2. Example: If a defect related to a shopping cart's performance is resolved, Sanity Testing would involve checking only the cart flow rather than the entire application.
  3. Significance: This testing serves as a checkpoint that helps testers decide whether to proceed with deeper, more extensive testing.
  4. Note: The term 'sanity' refers to the rational evaluation of the system's functionality post-fix.

In summary, Sanity Testing is an essential step that ensures the software's reliability after minor changes, enabling testers to identify any immediate issues before a comprehensive testing effort is initiated.

Purpose: A focused test to check if a specific function or bug fix works.

Detailed Explanation

Sanity Testing is conducted to ensure that a particular feature or bug fix operates correctly. The focus is on specific areas to verify that the reported issues have been resolved without affecting other functionalities. This type of testing does not encompass comprehensive testing but rather aims for a quick assessment!

Examples & Analogies

Think of Sanity Testing like checking a door lock before you open the door. You want to make sure that just the lock mechanism is functioning correctly, and you aren't trying to assess the entire door installation or the surrounding wall.

Example: A defect in the cart page is fixed → test the cart flow only.

Detailed Explanation

In this scenario, if there was a malfunction in the cart functionality of an e-commerce site (for instance, items were not being added to the cart properly), once the bug is fixed, Sanity Testing specifically targets the cart flow. Testers would only verify the functionality of adding, modifying, or removing items from the cart to confirm that the fix works as intended, rather than testing the entire website.

Examples & Analogies

Imagine a car mechanic who has just repaired the brakes of a car. Instead of taking the car through a full test drive (which would include checking the engine, tires, etc.), the mechanic would first check only the brakes to see if they work properly, ensuring that the specific problem has been addressed.

Significance of Sanity Testing

Note: Sanity = “Are we sane to proceed with deeper testing?”

Detailed Explanation

Sanity Testing serves as a quick checkpoint to determine if a build is stable enough to continue with extensive testing. If the sanity test passes, it validates that the core functionality runs correctly, enabling other areas of testing to take place without wasting time on a faulty build.

Examples & Analogies

Consider Sanity Testing as a quick health check before surgery. Doctors perform initial assessments to ensure that patients are fit to undergo the procedure. If the patient isn't stable, there's no point in proceeding with complex surgeries. Similarly, Sanity Testing helps determine if further, more in-depth testing can be safely conducted.
