Understanding Jenkins Test Result Trend Graph

In Jenkins, after running multiple builds with tests, the Test Result Trend graph shows the number of test failures over time. What does a downward slope in this graph indicate?

A The number of tests executed is increasing over builds

B The number of test failures is increasing over builds

C The build duration is decreasing over builds

D The number of test failures is decreasing over builds

💡 Hint

Think about what a downward slope means for a count of failures.

A downward slope in the Test Result Trend graph means fewer tests are failing as builds progress, showing improvement in test stability.

Purpose of Test Result Trend in Jenkins

What is the main purpose of the Test Result Trend feature in Jenkins?

A To monitor CPU usage during test execution

B To display the list of tests executed in the last build

C To track the number of test failures and successes over multiple builds

D To configure test execution order

💡 Hint

Think about what trend means in the context of test results.

The Test Result Trend shows how test results change over time, helping teams see if tests are improving or regressing.

Interpreting Missing Test Result Trend Data

You notice that the Test Result Trend graph in Jenkins is empty after several builds. Which of the following is the most likely cause?

A The test reports are not being published or archived correctly

B The Jenkins server is offline

C The build scripts are running too fast

D The test results are all passing

💡 Hint

Think about what Jenkins needs to generate the trend graph.

If Jenkins does not receive or archive test reports, it cannot display test trends, resulting in an empty graph.

Steps to Enable Test Result Trend in Jenkins Pipeline

Which sequence of steps correctly enables test result trend tracking in a Jenkins Pipeline?

A 1,2,3,4

B 2,1,3,4

C 1,3,2,4

D 3,1,2,4

💡 Hint

Think about the logical order: generate reports, publish them, archive, then view trends.

First, tests run and generate reports. Then the 'junit' step publishes results so Jenkins can process them. Archiving keeps reports for history. Finally, trends appear in the dashboard.

Best Practice for Maintaining Accurate Test Result Trends

Which practice best ensures that Jenkins Test Result Trend graphs accurately reflect test stability over time?

A Running tests only on demand to reduce load on Jenkins

B Consistently publishing test reports after every build and cleaning old reports properly

C Disabling archiving of test reports to save disk space

D Ignoring flaky tests to keep failure counts low

💡 Hint

Think about what Jenkins needs to track trends reliably.

Publishing reports every build and managing old data ensures trends are based on complete and accurate test results.
