Extent Reports setup in Selenium Java - Practice Problems & Coding Challenges

Challenge - 5 Problems

What is the output of this Extent Reports setup code?

Consider the following Java code snippet that initializes Extent Reports in a Selenium test. What will be the output in the generated report after running this code?

Selenium Java

ExtentReports extent = new ExtentReports();
ExtentTest test = extent.createTest("Login Test");
test.pass("Login successful");
extent.flush();

A No report generated because ExtentReports object was not configured with a reporter.

B A report with no tests because extent.flush() was called before creating the test.

C A report with one test named 'Login Test' marked as failed with message 'Login successful'.

D A report with one test named 'Login Test' marked as passed with message 'Login successful'.

💡 Hint

ExtentReports requires a reporter (like ExtentHtmlReporter) to be attached via attachReporter() before flush() generates a file.

No report is generated because the ExtentReports object was not configured with a reporter (e.g., ExtentHtmlReporter attached via attachReporter()). Without it, extent.flush() does not create any report file.

❓ assertion

intermediate

Which assertion correctly verifies the test status in Extent Reports?

You want to verify in your Selenium test that the ExtentTest status is marked as FAIL after a failed login attempt. Which assertion is correct?

Selenium Java

ExtentTest test = extent.createTest("Login Test");
test.fail("Login failed due to invalid credentials");

A assertEquals(test.getStatus(), Status.FAIL);

B assertTrue(test.getStatus().equals("FAIL"));

C assertFalse(test.getStatus() == Status.PASS);

D assertNull(test.getStatus());

💡 Hint

Check the ExtentTest API for how status is represented.

ExtentTest.getStatus() returns an enum Status. Comparing it with Status.FAIL using assertEquals is the correct way.

Why does this Extent Reports setup not generate any report file?

Review the following Java code snippet. Why does it fail to generate the Extent Report file?

Selenium Java

ExtentReports extent = new ExtentReports();
ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("report.html");
ExtentTest test = extent.createTest("Sample Test");
test.pass("Test passed");
// Missing extent.attachReporter(htmlReporter);
extent.flush();

A Because flush() must be called before creating tests.

B Because ExtentHtmlReporter requires a full file path, not just a file name.

C Because test.pass() must be called after flush().

D Because extent.attachReporter(htmlReporter) was not called, so no reporter is attached to write the report.

💡 Hint

Check if the reporter is attached to the ExtentReports object.

Without attaching the reporter using extent.attachReporter(htmlReporter), ExtentReports does not know where to write the report, so no file is generated.

❓ framework

advanced

Which Extent Reports setup is best for parallel test execution in Selenium?

You want to run Selenium tests in parallel and generate a single Extent Report. Which setup ensures thread-safe logging?

A Create a new ExtentReports instance inside each test thread without sharing, then merge reports manually.

B Use a ThreadLocal<ExtentTest> to store test instances per thread and attach a single ExtentReports instance with synchronized flush.

C Use static ExtentTest variables shared across threads without synchronization.

D Call extent.flush() after each test method without thread safety considerations.

💡 Hint

Think about how to keep test logs separate per thread safely.

Using ThreadLocal allows each thread to have its own test instance, avoiding conflicts. A single ExtentReports instance is shared and flushed safely after all tests.

🧠 Conceptual

expert

What is the primary purpose of calling extent.flush() in Extent Reports?

In the Extent Reports lifecycle, what does the method extent.flush() do?

A It initializes the ExtentReports object and prepares it for logging tests.

B It resets all test statuses to default before starting new tests.

C It writes all the logged test information to the report file and clears the internal buffer.

D It closes the Selenium WebDriver session after tests complete.

💡 Hint

Think about when the report file gets updated with test results.

Calling extent.flush() writes all accumulated test logs to the report file. Without it, the report file remains empty or incomplete.
