- What is a test plan?
A test plan is a document that outlines the testing strategy and approach for a specific project. A test plan includes the testing objectives, scope, schedule, resources, and test cases. Test plans are important to ensure that the testing is structured and thorough.
- What is a defect?
A defect is an error or issue in the software that causes it to not function correctly. Defects are identified through testing and must be fixed before the software can be released.
- What is a bug report?
A bug report is a document that outlines a defect or issue in the software. A bug report includes a description of the issue, steps to reproduce the issue, and any supporting documentation or screenshots. Bug reports are used to communicate defects to the development team and ensure that they are fixed.
- What is the difference between a test script and a test case?
A test case is a set of instructions that are used to test a specific aspect of the software. A test script is a set of instructions that are used to automate the testing process. Test scripts are often used in automated testing, while test cases are used in manual testing.
- What is the difference between black box testing and white box testing?
Black box testing is a type of testing where the tester does not have access to the internal workings of the software. The tester tests the software based on its inputs and outputs. White box testing is a type of testing where the tester has access to the internal workings of the software. The tester tests the software based on its code and structure.
- What is a test environment?
A test environment is the environment in which testing is performed. The test environment includes the hardware, software, and network configurations that are used for testing. The test environment should be set up to replicate the production environment as closely as possible.
- What is a test harness?
A test harness is a set of tools and utilities that are used to automate testing. Test harnesses are often used in automated testing to manage the test cases and execute the tests.
- What is a test log?
A test log is a document that records the results of testing. The test log includes the test cases that were executed, the results of each test, and any defects or issues that were identified. Test logs are important to track the progress of testing and ensure that all tests are completed.
- What is the difference between a test strategy and a test plan?
A test strategy is a high-level document that outlines the testing approach and objectives for a specific project. A test plan is a detailed document that outlines the testing strategy and approach for a specific project. Test strategies are used to guide the development of the test plan.
