What should be considered when developing effective automated tests for web applications?

When developing effective automated tests for web applications, it is important to consider the following points:

• Test stability: avoid fragile locators (use unique ids, data-attributes), minimize dependency on load times.
• Test isolation: each test should be independent to not affect others.
• Coverage of critical scenarios: test main user flows and business logic.
• Use of waits: apply explicit waits for elements to avoid errors due to asynchrony.
• Maintainability: write readable and reusable test code, use the Page Object Model for organization.
• Automation in CI/CD: integrate tests into the pipeline for regular execution.
• Logging and reports: provide clear reports on test results for quick analysis.

Example of using wait in Selenium (Java):

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("submitBtn")));
element.click();
