In white box testing, code coverage is a metric that shows how much of an application's source code has been executed by unit tests. It's a way to verify how much of the application's logic has been tested and executed. Code coverage is a key tool for analyzing software and measuring the effectiveness of its codebase. It can be used to guide the development of test cases to ensure that all parts of the code are tested. Code coverage tools use static instrumentation to insert statements that monitor code execution at critical points in the code. This can increase the execution time and code length, but the extra code provides valuable information to the tester. Code coverage scripts generate a report that details how much of the application code has been executed. read less

Smoke testing and sanity testing are both software testing methods, but they differ in scope, purpose, and depth of testing: Smoke testing Focuses on the overall stability of a software build, covering basic functionalities and critical pathways. Smoke testing is a quick evaluation that's used to verify that a system is ready for further testing. Sanity testing Focuses on specific areas of a software build, such as newly implemented features or recently fixed bugs. Sanity testing is used to confirm that a small change to the system hasn't caused any unintended side effects. Here are some more differences between smoke testing and sanity testing: Who performs the testing Software developers or testers perform smoke testing, while testers alone perform sanity testing. Documentation Smoke testing is documented or scripted, while sanity testing is not. Type of testing Smoke testing is a subset of acceptance testing, while sanity testing is a subset of regression testing. When testing occurs Sanity testing can be used as a type of mid-sprint QA in agile development shops. read less

Yes, you write test cases for smoke testing: Manual smoke testing: Testers manually develop and update test cases, and write test scripts for new or existing features. Hybrid smoke testing: Testers write test cases manually, and then automate them using a tool. Automated smoke testing: Software tools automate the smoke testing process. Smoke testing is a preliminary check to ensure that a software build's core functionality is working properly. It's often performed before major code changes or refactoring, or as part of a CI/CD pipeline. Here are some tips for writing test cases for smoke testing: Consider core functionalities: Make a list of the software's core functionalities, and consider which are essential for running and using the software. Keep the number of test cases manageable: A recommended number of test cases is between 20 and 50. Automate some of the tests: Automation can make the testing process more efficient, and the tests will run faster and more consistently. read less

The purpose of a smoke test is to identify major issues in software early in the development process. The goal is to prevent wasting time and resources on deeper tests of a broken product. Here are some other purposes of smoke testing: Early warning system Smoke testing acts as an early warning system for critical bugs that could disrupt the software's core functionalities. Save time and resources Smoke testing is a quick way to save time and resources in the development process. Enhance software quality Smoke testing helps enhance software quality and user satisfaction by detecting issues early. Validate accuracy Smoke testing validates the accuracy of the system in its early stages. Ensure adherence to requirements Smoke testing ensures that the system aligns with predefined criteria and adheres to specified requirements. Smoke testing is also known as build verification testing or confidence testing. read less

Smoke testing is typically done before production release, as a final check to ensure that the software application is stable and functional enough to be released to end-users. _Smoke Testing:_ Smoke testing is a type of testing that involves a series of high-level tests to ensure that the most critical functionalities of a software application are working as expected. The goal of smoke testing is to verify that the build or deployment is stable and functional enough to continue testing. _Purpose of Smoke Testing:_ The purpose of smoke testing is to: 1. _Verify build integrity_: Ensure that the build or deployment is complete and correct. 2. _Detect critical defects_: Identify critical defects that could prevent the software from functioning correctly. 3. _Reduce testing time_: Focus on the most critical functionalities and reduce the overall testing time. _Timing of Smoke Testing:_ Smoke testing is typically performed: 1. _After unit testing and integration testing_: Once the individual units of code have been tested and integrated, smoke testing is performed to ensure that the build is stable. 2. _Before system testing and acceptance testing_: Smoke testing is performed before more extensive testing, such as system testing and acceptance testing, to ensure that the software is stable enough for further testing. 3. _Before production release_: Smoke testing is performed as a final check before releasing the software to production, to ensure that it meets the required standards. By performing smoke testing before production release, you can ensure that your software application is stable, functional, and meets the required standards, reducing the risk of defects and errors in production. Do you have any further questions about smoke testing or its timing? read less

Black box testing focuses on the external behavior of the software, testing functionality without knowing the internal code. White box testing examines the internal structure and logic of the code, testing based on the source code.
