JUnit is a testing framework for Java, mostly focused for unit testing.
It is also used for writing integration and acceptance tests, making use of other libraries such as Selenium.
JUnit was massively used by the Java community and thus, its XML test result reports have become a de facto standard for test result reporting.
JUnit Basic Concepts
In JUnit, you have Tests and (Test) Suites. A Suite is a way of aggregating a group of tests, along with their results. This applies not just to the original Java’s JUnit but also for other implementations that generate the JUnit XML report.
In Java, Tests are created within a Test Case class, which contain the Tests, implemented as class methods (and properly annotated).
The Test Case classes may be grouped in Test Suites.
JUnit provides way more concepts (Test Runners, Test Fixtures, Categories, etc.) although they are not relevant in this context.
Importing JUnit XML reports
Below is a simplified example of a JUnit XML report containing a Test Suite with one Test Case.
The simplified tags hierarchy of these reports can be represented in the following diagram:
JUnit’s Test Cases are identified by the pair of attributes “classname” and “name” attributes.
Test Cases are imported to Xray’s Generic Test issues, and the “classname” and “name” attributes are concatenated and mapped to the Generic Test Definition field of the Generic Test.
If a Test already exists with the same Generic Test Definition, then a duplicate is not created.
Test Cases are imported to a new (or user-specified) Test Execution in the context of some project, along with their respective execution results.
JUnit’s Test Suites are not mapped to any special entity. However, the execution details screen will show the Test Suite related to a specific test result.
The status of the Test Run will be set based on the Test Case result:
without failures, errors, and weren’t skipped
Note: Test Cases with the status FAIL may have an error/failure message, which can be seen in the Test Run screen, under the Results section.
If the same Test Case has been executed on multiple Test Suites, then the result for each Test Suite will be shown.
When a Test Case is executed in multiple Test Suites, the overall status of the Test Run will be calculated as a joint value.
Overall status of the Test Run
If all the mapped results of the Test Case were PASS
If any of the mapped results of the Test Case was FAIL
Linking Tests with Requirements
Although this is not yet included by JUnit, Xray supports a customized version of the JUnit report format for linking Requirement issues with Test cases.
Two scenarios are supported:
- The requirement key is passed as an attribute on the "testcase" XML element named "requirement"
- The requirement key is passed as a new property element beneath the "testcase" element, on a dedicated properties element.
