Output of ExtentReports Configuration Code

What will be the title of the report generated by the following ExtentReports configuration code snippet?

Selenium Java

ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("extent.html");
htmlReporter.config().setDocumentTitle("My Test Report");
ExtentReports extent = new ExtentReports();
extent.attachReporter(htmlReporter);
extent.createTest("Sample Test").pass("Test passed successfully");
extent.flush();

A My Test Report

B Sample Test

C extent.html

D Test passed successfully

💡 Hint

Look at the method that sets the document title in the htmlReporter configuration.

The method setDocumentTitle sets the title of the HTML report document. Here, it is set to "My Test Report". Other strings are test name, file name, or test status messages, not the document title.

❓ assertion

Correct Assertion for Extent Test Status

Which assertion correctly verifies that an ExtentTest has passed after execution?

Selenium Java

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

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

B assertTrue(test.getStatus() == Status.FAIL);

C assertNull(test.getStatus());

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

💡 Hint

Check the status set by the pass() method and compare it correctly.

Calling test.pass() sets the test status to PASS. So the assertion must check that test.getStatus() equals Status.PASS.

Best Locator for Customizing Extent Report Theme

In ExtentHtmlReporter configuration, which method correctly sets the theme to DARK mode?

A htmlReporter.setConfig("theme", "dark");

B htmlReporter.setTheme("dark");

C htmlReporter.config().theme = "dark";

D htmlReporter.config().setTheme(Theme.DARK);

💡 Hint

Check the official ExtentHtmlReporter API for setting themes.

The correct method is config().setTheme() with Theme enum values. Other options are invalid or do not exist.

Identify the Error in Extent Report Initialization

What error will occur when running this ExtentReports initialization code?

Selenium Java

ExtentReports extent = new ExtentReports();
ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter();
extent.attachReporter(htmlReporter);

A IllegalArgumentException due to missing file path

B NullPointerException at attachReporter

C Compilation error: No suitable constructor found for ExtentHtmlReporter()

D No error, code runs successfully

💡 Hint

Check the constructors available for ExtentHtmlReporter.

ExtentHtmlReporter requires a file path string in its constructor. Calling new ExtentHtmlReporter() without arguments causes a compilation error.

Customizing Extent Report with System Info and Multiple Tests

Given the following code snippet, what will be the value of the system info key "OS" in the generated report?

Selenium Java

ExtentReports extent = new ExtentReports();
ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("report.html");
extent.attachReporter(htmlReporter);
extent.setSystemInfo("OS", "Windows 10");
ExtentTest test1 = extent.createTest("Test 1");
test1.pass("Step 1 passed");
ExtentTest test2 = extent.createTest("Test 2");
test2.fail("Step 2 failed");
extent.flush();

A null

B Windows 10

C Step 1 passed

D Test 1

💡 Hint

System info is set once on the ExtentReports object and is global for the report.

setSystemInfo adds key-value pairs to the report metadata. Here, "OS" is set to "Windows 10" and appears in the report info section.

Practice

1. What is the main purpose of customizing an Extent report in Selenium Java?

easy

A. To make test results clearer and easier to understand

B. To increase the speed of test execution

C. To reduce the size of the test scripts

D. To automatically fix test failures

Solution

1. Step 1: Understand Extent report role

   Extent reports show test results in a readable format.

2. Step 2: Identify customization benefits

   Customization helps make these results clearer and more useful.

3. Final Answer:

   To make test results clearer and easier to understand -> Option A

4. Quick Check:

   Customization = clearer test results [OK]

Hint: Think: Why improve report look? To understand results better [OK]

Common Mistakes:

• Confusing report customization with test speed
• Thinking customization changes test logic
• Assuming customization fixes test errors

2. Which code snippet correctly sets the theme of an Extent report to DARK in Selenium Java?

easy

A. extentHtmlReporter.config().setTheme(Theme.DARK);

B. extentHtmlReporter.setTheme("dark");

C. extentHtmlReporter.config().theme = "dark";

D. extentHtmlReporter.setConfigTheme(Theme.DARK);

Solution

1. Step 1: Recall ExtentReports theme setting syntax

   Use config() method and setTheme with Theme enum.

2. Step 2: Match correct method and enum usage

   Only extentHtmlReporter.config().setTheme(Theme.DARK); uses config().setTheme(Theme.DARK) correctly.

3. Final Answer:

   extentHtmlReporter.config().setTheme(Theme.DARK); -> Option A

4. Quick Check:

   Use config().setTheme(Theme.DARK) [OK]

Hint: Remember: config() then setTheme with Theme enum [OK]

Common Mistakes:

• Using setTheme directly without config()
• Passing theme as string instead of Theme enum
• Using incorrect method names

3. Given the following code snippet, what will be the title of the generated Extent report?

ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("testReport.html");
htmlReporter.config().setDocumentTitle("My Test Report");
ExtentReports extent = new ExtentReports();
extent.attachReporter(htmlReporter);

medium

A. Extent Report

B. testReport.html

C. My Test Report

D. Default Title

Solution

1. Step 1: Identify method setting report title

   config().setDocumentTitle("My Test Report") sets the HTML page title.

2. Step 2: Understand effect on report

   The report's browser tab will show "My Test Report" as title.

3. Final Answer:

   My Test Report -> Option C

4. Quick Check:

   setDocumentTitle sets report title [OK]

Hint: Look for setDocumentTitle method for report title [OK]

Common Mistakes:

• Confusing file name with report title
• Assuming default title is used
• Ignoring config() method effects

4. Identify the error in the following code that prevents the Extent report from saving properly:

ExtentHtmlReporter reporter = new ExtentHtmlReporter("report.html");
ExtentReports extent = new ExtentReports();
extent.attachReporter(reporter);
// Missing flush call

medium

A. ExtentHtmlReporter should be initialized after ExtentReports

B. Incorrect file name extension, should be .txt

C. attachReporter method is deprecated and should not be used

D. Missing call to extent.flush() to save the report

Solution

1. Step 1: Check report saving process

   Extent report requires extent.flush() to write data to file.

2. Step 2: Identify missing flush call

   The code does not call extent.flush(), so report is not saved.

3. Final Answer:

   Missing call to extent.flush() to save the report -> Option D

4. Quick Check:

   Always call extent.flush() to save report [OK]

Hint: Remember to call extent.flush() after tests [OK]

Common Mistakes:

• Forgetting to call flush()
• Changing file extension incorrectly
• Misunderstanding attachReporter usage

5. You want to add system information like OS and Java version to your Extent report. Which code snippet correctly adds this info before flushing the report?

ExtentReports extent = new ExtentReports();
ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("sysInfoReport.html");
extent.attachReporter(htmlReporter);
// Add system info here
extent.flush();

hard

A. htmlReporter.setSystemInfo("OS", System.getProperty("os.name"));
htmlReporter.setSystemInfo("Java Version", System.getProperty("java.version"));

B. extent.addSystemInfo("OS", System.getProperty("os.name"));
extent.addSystemInfo("Java Version", System.getProperty("java.version"));

C. extent.setSystemInfo("OS", System.getProperty("os.name"));
extent.setSystemInfo("Java Version", System.getProperty("java.version"));

D. htmlReporter.addSystemInfo("OS", System.getProperty("os.name"));
htmlReporter.addSystemInfo("Java Version", System.getProperty("java.version"));

Solution

1. Step 1: Identify correct method to add system info

   ExtentReports class has addSystemInfo method to add info.

2. Step 2: Confirm usage on ExtentReports instance

   System info is added on extent, not on htmlReporter.

3. Final Answer:

   extent.addSystemInfo("OS", System.getProperty("os.name")); extent.addSystemInfo("Java Version", System.getProperty("java.version")); -> Option B

4. Quick Check:

   Use extent.addSystemInfo() before flush [OK]

Hint: Add system info on extent, not htmlReporter [OK]

Common Mistakes:

• Calling setSystemInfo on htmlReporter instead of extent
• Using setSystemInfo which does not exist
• Adding system info after flush()
