TestNG default reports in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of TestNG default reports?

TestNG default reports provide a summary of test execution results, showing which tests passed, failed, or were skipped. They help quickly understand test outcomes without extra setup.

beginner

Where can you find TestNG default reports after running tests?

TestNG default reports are generated in the 'test-output' folder inside your project directory, typically as 'index.html' which you can open in a browser to view results.

intermediate

What are the main sections shown in the TestNG default HTML report?

The main sections include: Summary (test counts and status), Groups (test groups run), Reporter output (logs), and Results (detailed test case info).

beginner

How does TestNG categorize test results in its default report?

TestNG categorizes tests as Passed, Failed, or Skipped based on execution. Passed tests ran successfully, Failed tests had errors, and Skipped tests were not run due to dependencies or conditions.

intermediate

Can you customize TestNG default reports without external tools?

TestNG default reports have limited customization. For advanced reports, you can use listeners or external libraries like ReportNG or Allure, but default reports are mostly fixed.

Where does TestNG save its default reports after test execution?

A In the 'bin' folder

B In the 'test-output' folder

C In the 'src' folder

D In the 'lib' folder

TestNG saves default reports in the 'test-output' folder inside your project directory.

Which of these is NOT a test status shown in TestNG default reports?

A In Progress

B Failed

C Skipped

D Passed

TestNG default reports show Passed, Failed, and Skipped tests. 'In Progress' is not a status shown.

What file format is the main TestNG default report?

A .txt

B .json

C .html

D .xml

The main TestNG default report is an HTML file, usually named 'index.html'.

Which section in TestNG default reports shows detailed test case results?

A Results

B Groups

C Summary

D Reporter output

The 'Results' section shows detailed information about each test case.

Can you fully customize TestNG default reports without extra tools?

A Yes, easily

B Only by changing Java code

C Only by editing XML files

D No, they have limited customization

TestNG default reports have limited customization; advanced customization requires external tools or listeners.

Explain the main features and sections of TestNG default reports.

Think about what you see when you open the index.html report.

Describe how TestNG default reports help in understanding test execution outcomes.

Consider why reports are useful after running tests.

Practice

1. What is the main purpose of TestNG default reports?

easy

A. To write custom test cases manually

B. To automatically show test results after running tests

C. To compile Java code before testing

D. To create database backups

Solution

1. Step 1: Understand what TestNG default reports do

   TestNG default reports automatically display the results of tests after execution without extra coding.

2. Step 2: Compare options with this function

   Only To automatically show test results after running tests matches this description; others describe unrelated tasks.

3. Final Answer:

   To automatically show test results after running tests -> Option B

4. Quick Check:

   TestNG default reports = automatic test result display [OK]

Hint: Default reports show results automatically after tests run [OK]

Common Mistakes:

• Thinking reports require extra code
• Confusing reports with code compilation
• Assuming reports manage databases

2. Which file is generated by TestNG by default to show test results?

easy

A. test-output/index.html

B. src/test/java/Test.java

C. pom.xml

D. log.txt

Solution

1. Step 1: Identify the default report file location

   TestNG generates reports inside the 'test-output' folder, with 'index.html' as the main report file.

2. Step 2: Check other options for correctness

   Other files are unrelated: source code, build config, or logs.

3. Final Answer:

   test-output/index.html -> Option A

4. Quick Check:

   Default report file = test-output/index.html [OK]

Hint: Look inside test-output folder for default reports [OK]

Common Mistakes:

• Confusing source code files with report files
• Expecting reports in pom.xml or logs
• Not checking the test-output directory

3. Given this TestNG test run, what will the default report show if one test fails and two pass?

medium

A. Passed: 2, Failed: 1, Skipped: 0

B. Passed: 3, Failed: 0, Skipped: 0

C. Passed: 1, Failed: 2, Skipped: 0

D. Passed: 0, Failed: 3, Skipped: 0

Solution

1. Step 1: Analyze the test results given

   There are two tests that passed and one test that failed.

2. Step 2: Match the counts to the report format

   The report shows counts as Passed: 2, Failed: 1, Skipped: 0.

3. Final Answer:

   Passed: 2, Failed: 1, Skipped: 0 -> Option A

4. Quick Check:

   Test counts in report = Passed 2, Failed 1 [OK]

Hint: Count tests passed and failed to match report summary [OK]

Common Mistakes:

• Mixing passed and failed counts
• Assuming skipped tests when none exist
• Misreading the test result numbers

4. You ran TestNG tests but the default report shows no tests executed. What is the likely cause?

medium

A. Java version is outdated

B. TestNG jar file is corrupted

C. Report folder is manually deleted

D. Test methods are missing the @Test annotation

Solution

1. Step 1: Understand why no tests run

   If test methods lack the @Test annotation, TestNG will not recognize or run them.

2. Step 2: Evaluate other options

   Corrupted jar or Java version issues usually cause errors, not silent no tests. Deleting report folder does not affect test execution.

3. Final Answer:

   Test methods are missing the @Test annotation -> Option D

4. Quick Check:

   No @Test annotation = no tests run [OK]

Hint: Check @Test annotation on test methods first [OK]

Common Mistakes:

• Assuming report folder deletion stops tests
• Blaming Java version without error messages
• Ignoring missing @Test annotations

5. How can you customize the TestNG default report to include screenshots on failure?

hard

A. By disabling default reports and writing logs to console only

B. By editing the test-output/index.html file manually after tests run

C. By adding listeners and embedding screenshots in the report via ITestListener

D. By renaming the test-output folder before running tests

Solution

1. Step 1: Understand default report customization

   TestNG default reports do not support screenshots by default; customization requires listeners like ITestListener.

2. Step 2: Evaluate options for adding screenshots

   Adding listeners to capture screenshots on failure and embed them is the correct approach. Manual editing or renaming folders won't add screenshots. Disabling reports removes them entirely.

3. Final Answer:

   By adding listeners and embedding screenshots in the report via ITestListener -> Option C

4. Quick Check:

   Use ITestListener to add screenshots [OK]

Hint: Use ITestListener to add screenshots on failure [OK]

Common Mistakes:

• Trying to edit report files manually
• Renaming folders expecting new features
• Disabling reports instead of customizing
