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

Challenge - 5 Problems

❓ Predict Output

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.

Practice

1. What is the primary purpose of using ExtentHtmlReporter in Selenium Java testing?

easy

A. To execute Selenium WebDriver tests

B. To locate web elements on a page

C. To generate an HTML report for test execution results

D. To manage browser windows during tests

Solution

1. Step 1: Understand the role of ExtentHtmlReporter

   ExtentHtmlReporter is used to create a visual HTML report that shows test results clearly.

2. Step 2: Differentiate from other components

   It does not run tests or interact with browsers; it only formats and outputs reports.

3. Final Answer:

   To generate an HTML report for test execution results -> Option C

4. Quick Check:

   ExtentHtmlReporter = HTML report generator [OK]

Hint: ExtentHtmlReporter creates HTML reports, not test execution [OK]

Common Mistakes:

• Confusing ExtentHtmlReporter with WebDriver
• Thinking it runs tests
• Assuming it manages browser actions

2. Which of the following is the correct way to initialize ExtentReports with ExtentHtmlReporter in Java?

easy

A. ExtentReports extent = new ExtentReports(); extent.createReporter("report.html");

B. ExtentHtmlReporter reporter = new ExtentHtmlReporter("report.html"); ExtentReports extent = new ExtentReports(); extent.attachReporter(reporter);

C. ExtentHtmlReporter reporter = new ExtentHtmlReporter(); extent.attachReporter(reporter);

D. ExtentReports extent = new ExtentReports("report.html"); ExtentHtmlReporter reporter = new ExtentHtmlReporter();

Solution

1. Step 1: Create ExtentHtmlReporter with file path

   You must instantiate ExtentHtmlReporter with the report file name or path.

2. Step 2: Attach reporter to ExtentReports instance

   Create ExtentReports object and attach the reporter using attachReporter method.

3. Final Answer:

   ExtentHtmlReporter reporter = new ExtentHtmlReporter("report.html"); ExtentReports extent = new ExtentReports(); extent.attachReporter(reporter); -> Option B

4. Quick Check:

   Initialize reporter with path, then attach to ExtentReports [OK]

Hint: Create reporter with path, then attach to ExtentReports [OK]

Common Mistakes:

• Not passing file path to ExtentHtmlReporter constructor
• Calling attachReporter before creating ExtentReports
• Using non-existent methods like createReporter

3. Given the following code snippet, what will be the output in the Extent Report after execution?

ExtentHtmlReporter reporter = new ExtentHtmlReporter("testReport.html");
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
ExtentTest test = extent.createTest("LoginTest");
test.pass("Login successful");
extent.flush();

medium

A. The report will show a test named 'LoginTest' marked as failed.

B. The report will be empty because flush() is called before creating the test.

C. The code will throw a runtime exception due to missing test initialization.

D. The report will show a test named 'LoginTest' marked as passed with message 'Login successful'.

Solution

1. Step 1: Analyze test creation and logging

   The test 'LoginTest' is created and logged as passed with message 'Login successful'.

2. Step 2: Understand flush() role

   Calling extent.flush() writes the report to the file including all logged tests.

3. Final Answer:

   The report will show a test named 'LoginTest' marked as passed with message 'Login successful'. -> Option D

4. Quick Check:

   createTest + pass + flush = Passed test in report [OK]

Hint: Create test, log pass, then flush to save report [OK]

Common Mistakes:

• Thinking flush() clears tests
• Assuming test is failed without fail() call
• Believing report is empty without flush()

4. Identify the error in the following Extent Reports setup code:

ExtentHtmlReporter reporter = new ExtentHtmlReporter();
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
ExtentTest test = extent.createTest("SearchTest");
test.pass("Search executed");
extent.flush();

medium

A. ExtentHtmlReporter must be initialized with a file path in its constructor.

B. ExtentReports cannot attach more than one reporter.

C. createTest() method requires two parameters.

D. flush() should be called before creating tests.

Solution

1. Step 1: Check ExtentHtmlReporter initialization

   ExtentHtmlReporter requires a file path string in its constructor to specify report output location.

2. Step 2: Verify other method usages

   attachReporter, createTest, and flush are used correctly; no multiple reporter restriction or parameter issues.

3. Final Answer:

   ExtentHtmlReporter must be initialized with a file path in its constructor. -> Option A

4. Quick Check:

   Reporter needs file path on creation [OK]

Hint: Always give file path when creating ExtentHtmlReporter [OK]

Common Mistakes:

• Omitting file path in ExtentHtmlReporter constructor
• Misunderstanding createTest parameters
• Calling flush too early

5. You want to create an Extent Report that logs multiple tests and marks one as failed with a custom error message. Which code snippet correctly sets up the report and logs these results?

hard

A. ExtentHtmlReporter reporter = new ExtentHtmlReporter("multiTestReport.html");
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
ExtentTest test1 = extent.createTest("Test1");
test1.pass("Test1 passed");
ExtentTest test2 = extent.createTest("Test2");
test2.fail("Test2 failed due to timeout");
extent.flush();

B. ExtentReports extent = new ExtentReports("multiTestReport.html");
ExtentHtmlReporter reporter = new ExtentHtmlReporter();
extent.createTest("Test1").pass("Test1 passed");
extent.createTest("Test2").fail("Test2 failed due to timeout");
extent.flush();

C. ExtentHtmlReporter reporter = new ExtentHtmlReporter();
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
extent.createTest("Test1").pass("Test1 passed");
extent.createTest("Test2").fail("Test2 failed due to timeout");
extent.flush();

D. ExtentHtmlReporter reporter = new ExtentHtmlReporter();
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
ExtentTest test1 = extent.createTest("Test1");
test1.fail("Test1 failed");
ExtentTest test2 = extent.createTest("Test2");
test2.pass("Test2 passed");
extent.flush();

Solution

1. Step 1: Initialize ExtentHtmlReporter with file path

   Instantiate ExtentHtmlReporter with the path to the report file, create an ExtentReports instance, and attach the reporter.

2. Step 2: Create multiple tests and log statuses

   Create ExtentTest instances with createTest(), log one with pass("message") and one with fail("custom error message"), then flush().

3. Final Answer:

   ExtentHtmlReporter reporter = new ExtentHtmlReporter("multiTestReport.html"); ExtentReports extent = new ExtentReports(); extent.attachReporter(reporter); ExtentTest test1 = extent.createTest("Test1"); test1.pass("Test1 passed"); ExtentTest test2 = extent.createTest("Test2"); test2.fail("Test2 failed due to timeout"); extent.flush(); -> Option A

4. Quick Check:

   Reporter with path + attach + pass/fail + flush [OK]

Hint: Attach reporter with path, create tests, log pass/fail, then flush [OK]

Common Mistakes:

• Not passing file path to ExtentHtmlReporter
• Swapping pass and fail calls
• Calling flush before logging tests
