Performing unit and integration testing

# Performing Unit and Integration Testing Unit and integration testing are essential activities during the software development process. Unit testing is the process of testing individual components of the system to ensure their functionality. Integration testing is the process of testing the combined components of the system to ensure their compatibility and proper functioning. Both unit and integration tests are important for ensuring the quality of a software system. Unit testing is done by breaking down the system into its individual components and testing each component individually. This helps to identify any bugs or errors that may exist in a single component before they can be integrated into the system. Integration testing is done after the individual components have been tested, and the components have been combined into a single system. This helps to ensure that the components integrate together properly and that the system functions as expected. Both unit and integration tests are important for ensuring the quality of a software system. Testing at each stage of the development process helps to identify any bugs or errors that may exist before they can be integrated into the system. It is important to ensure that the tests are well-defined and well-documented so that they are repeatable and reliable.

# Unit and Integration Testing Unit and integration testing are two important parts of software development. They help ensure that the code works as expected and can be deployed to production without any major issues. ## Algorithm 1. Identify the individual functional units of the code. 2. Create test cases that cover all possible scenarios for each unit. 3. Run the test cases and check if the expected results are achieved. 4. If there are any issues, debug and fix them. 5. Once all unit tests pass, perform integration tests to ensure that all the units work together correctly. 6. If any integration tests fail, debug and fix them. 7. Once all tests pass, the code can be deployed to production. ## Sample Code ``` // Identify the individual functional units function unit1() { // code } function unit2() { // code } // Create test cases test("unit1 should do something", () => { // test code }); test("unit2 should do something else", () => { // test code }); // Run the tests runTests(); // Check results assertResults(); // Debug and fix any issues debug(); // Run integration tests runIntegrationTests(); // Check results assertIntegrationResults(); // Debug and fix any issues debugIntegration(); // Deploy to production deploy(); ```
