Capture screenshots on failure

Capture a screenshot automatically whenever a test fails, before the driver quits.

1. 1Add a failure hook: JUnit 5 TestWatcher/AfterTestExecutionCallback, pytest_runtest_makereport, NUnit TearDown checking TestContext.CurrentContext.Result, or Mocha afterEach checking this.currentTest.state.
2. 2In the hook save a screenshot (TakesScreenshot / save_screenshot) as screenshots/<test-name>-<timestamp>.png.
3. 3Make sure the hook runs before driver.quit().
4. 4Sign in with qa@target.dev / Test@123 (#username, #password, #login-button). Assert the dashboard — the passing run produces no screenshot.

• A screenshot is captured from a failure hook
• The dashboard is shown
• At least 1 assertion passes
