How do you conduct testing?

I conduct testing according to predefined stages, adapting the process to the project's specifics:

1. Requirements and Documentation Analysis: I study technical documentation, specifications, and user stories to fully understand the functionality and non-functional requirements.

2. Test Planning: I define objectives, scope, choose strategies (e.g., functional, regression, load testing), tools, and create test documentation (test plan, test cases, checklists).

3. Development of Test Artifacts: I create test scenarios/cases, test data. For automation, I write scripts.

   // Example of a simple test case in Java using TestNG
   import org.testng.annotations.Test;
   import static org.testng.Assert.assertEquals;
   
   public class LoginTest {
   
       @Test
       public void testSuccessfulLogin() {
           // Test steps:
           // 1. Open login page
           // 2. Enter correct login and password
           // 3. Click the "Login" button
           // 4. Verify that the user is redirected to the main page
           String expectedUrl = "https://example.com/dashboard";
           String actualUrl = performLogin("validUser", "validPassword");
           assertEquals(actualUrl, expectedUrl, "Error during successful login");
       }
   
        private String performLogin(String username, String password) {
            // Implementation of login logic (via UI or API)
            // Returns the URL of the page after login attempt
            return "https://example.com/dashboard"; // Stub
        }
   }
   

4. Test Environment Preparation: I set up the necessary environment (test stands, databases, test data).

5. Test Execution: I perform the planned tests. Depending on the test type, these can be manual or automated runs. I record results and defects.

   # Example of running automated tests with pytest
   # In terminal:
   # pytest test_login.py
   
   # test_login.py
   import pytest
   
   def test_invalid_login():
       # Test steps:
       # 1. Open login page
       # 2. Enter incorrect login and password
       # 3. Click the "Login" button
       # 4. Verify that an error message appears
       error_message = get_login_error("invalidUser", "wrongPassword")
       assert "Invalid login or password" in error_message
       # assert "Invalid login or password" == error_message # More strict check
   
   def get_login_error(username, password):
       # Implementation of error message retrieval (via UI or API)
       return "Invalid login or password" # Stub
   

6. Results Analysis and Reporting: I analyze the test execution outcomes, document defects in a bug tracking system.

   ID	Short description of defect	Status	Severity	Priority	Reproduction steps	Expected result	Actual result
   101	"Cancel" button does not work	Open	Blocking	High	1. Open the edit form. 2. Click "Cancel".	The form should close.	The form remains open.
   102	Incorrect date format in report	In progress	Significant	Medium	1. Generate report.	Date should be in DD.MM.YYYY format.	Date is displayed in MM/DD/YYYY format.

7. Regression Testing: After fixing defects, I conduct regression testing to confirm that new changes did not introduce new errors and old defects remain fixed. I use a set of regression tests for automation.

8. Test Process Completion: I confirm the product's compliance with quality criteria, close the testing cycle for this version. I participate in retrospectives to analyze the work done and improve processes.

I actively use tools for test management (TestRail, Zephyr), bug tracking (Jira, Redmine), automation (Selenium, Cypress, Rest-Assured, Postman), and CI/CD (Jenkins, GitLab CI). I constantly interact with developers, analysts, and project managers.
