What skills and experience do you have in the field of software testing?

Skills and experience in software testing typically include:

• Writing unit tests using JUnit or TestNG to verify individual components.
• Using mock objects (Mockito, EasyMock) to isolate tested modules.
• Conducting integration testing to verify interaction between components.
• Automating UI testing (e.g., with Selenium or Espresso for Android).
• Knowledge of TDD (Test-Driven Development) and BDD principles.
• Experience working with CI/CD systems for automatic test execution.

For example, writing a simple unit test in JUnit:

@Test
public void testSum() {
    Calculator calc = new Calculator();
    int result = calc.sum(2, 3);
    assertEquals(5, result);
}
