What is the role of the DispatcherServlet component in the process of handling HTTP requests in Spring MVC web applications?

In deploying new features, to prevent missed testing, several methods can be used:

• Test automation: writing unit and integration tests that run automatically with each code change.
• Code review: mandatory review of code by colleagues to ensure tests are written and cover new features.
• CI/CD: setting up continuous integration that does not allow merging changes without passing tests.
• Test plans and checklists: documenting testing requirements for new features.
• Feature flags: deploying new features under flags to control activation and test gradually.

Example of automatic test execution in Android using Gradle:

// In build.gradle
android {
    testOptions {
        unitTests.all {
            it.useJUnitPlatform()
        }
    }
}

This allows running tests during project build and prevents code integration without passing tests.
