2. Technical Software testing Interview Questions:

2.1. What makes a good test case?

A standard and effective test case should clearly show the results the tester will achieve, including a clear title, a well-stated test purpose, a comprehensive description of the test subject, and specified testing conditions. Please give the most appropriate answer based on the suggestions above and combine it with your actual working process.

2.2. What do you understand about test cases and use cases?

  • Test case: A document that provides step-by-step instructions for testing an application, including detailed guidance on how to test, descriptions, comments, actions, and test case results.
  • Use case: A document that helps testers understand user actions in an application, including specific functions and the system’s response.

2.3. How many software testing methods are there?

There are three primary software testing methods applied today:

  • Black-box testing: Primarily detects technical parameter-related errors, and doesn’t require knowledge of internal paths, structure, or software deployment.
  • White-box testing: In contrast to black-box testing, white-box testing relies on internal links, code structure, and software deployment. So white box testing also requires advanced programming skills.
  • Gray-box testing: With this method, the tester doesn’t have much knowledge related to limitations or errors inside the program. 

2.4. What are the stages of software development?

Software development involves specific stages, and testers need to be familiar with them. You can answer the recruiter as follows:

The process will unfold from the unit testing stage until the errors have been fixed and accepted. This involves four main steps:

  • Unit testing: Checking individual small code units to ensure functionality and reliability.
  • Integration testing: Verifying the operation of code units when combined.
  • System testing: Testing the entire software system in a real-world environment.
  • Acceptance testing: Ensuring the software meets customer or end-user requirements.

2.5. What are the components of a test report?

In response to this question, list the components necessary for a test report:

  • Tester’s Name: The person conducting the test.
  • Project Name: The name of the project or product being tested.
  • Number of Test Cases: The total number of written or executed test cases.
  • Test Case Results: The number of test cases evaluated as Pass or Fail.
  • Defects in the Module: The number of errors or flaws detected in a specific module.
  • Progress in Bug Fixing: Information on the progress of fixing errors, including the number fixed and the remaining.

2.6. When should the testing process be stopped?

When faced with this question, you can cite several cases, such as:

  • Exceeding the testing time.
  • Running out of budget.
  • Meeting test case requirements and bug rates.
  • Errors found during testing have been fixed.
  • The product has few bugs, operates stably, and is good.
  • Testing is complete, and documentation is updated.
  • The project manager decides to stop testing
