JUnit
AIO Tests allows easy reporting of JUnit results by supporting the import of the TEST-feature-results.xml (the output file of a JUnit execution).
With AIO Tests JUnit integration, developers will not need to write manual cases inside AIO Tests. They can write JUnit cases which will be imported (created) in AIO Tests along with their execution results. This results in a holistic view of coverage of requirements (unit to manual to functional and end-to-end automated tests).
This article discusses how to import JUnit XML results and map it to existing cases in AIO Tests or generate new cases in AIO, in the absence of existing cases.

JUnit
JUnit is one of the most widely used open source Unit Testing Framework for JAVA and has been a key player in promoting test driven development.
The latest version of JUnit, JUnit 5 has introduced many new features, new APIs and the concept of test engine to simplify test automation (e.g. @DisplayName, @BeforeXX, @ParametrizedTest, etc.).
JUnit Reporting
JUnit’s XML report comes through the Maven Surefire plugin or through an ANT task.
Being one of the earliest testing frameworks and with a huge community base, JUnit’s XML report has got widespread adoption. Many continuous integration servers accept JUnit XML report as their de facto standard for reporting test results.
The report format gradually became ubiquitous for test results reporting and frameworks across languages like PyTest, Cucumber, Fitnesse, RSpec, Katalon etc. All these have reporting extensions which generate the JUnit XML report, which implies cases from any of these frameworks can be imported into AIO Tests.
Sample JUnit XML Report
Generating JUnit XML Report
Maven Surefire
Maven surefire plugin is required to generate the JUnit XML Report.
JUnit 4 Settings
JUnit 5 Settings
If the JUnit 5 features are being utilized, the junit-jupiter-engine needs to be added with additional configurations for fine grained configuration of reports.
Tests need to be annotated with @DisplayName and <usePhrasedXXXName>true</usePhrasedXXXName>
fields need to be set to true as shown below.
For more info, refer Maven Surefire - Using JUnit 5
Ant
If you are using Ant, following tasks need to be used to generate the report.
JUnit 4 - JUnit Task
JUnit 5 - JUnitlauncher Task
Using the junitlauncher
task allows launching the JUnit 5 test launcher and building the test requests to be executed by the test engine(s) supported by JUnit 5. For more information, please refer JUnitLauncher.
Status Mapping JUnit → AIO Tests
JUnit XML | Description | AIO Tests Mapping |
---|---|---|
No tag inside <testcase> means Passed | Passed case | Passed |
</skipped> | Skipped case either by @Ignore or others | Not Run |
</failure> |
| Failed |
</error> |
| Failed |
Mapping automated JUnit tests to AIO Tests
In going with the simplicity advantage of AIO Tests, the JUnit integration has been designed as a simple and non-intrusive integration, without any extra dependency or coding required.
There are 4 ways that a JUnit case is mapped to an AIO Case.
JUnit 5:
@DisplayName
gives a way to specify generic information in the test name instead of the hard rule based Java method names. This can be used to specify an existing AIO Case Key.
For example,@DisplayName("SCRUM-TC-1973 : Test forest gets created.")
Testcase key in Underscores : Since Java and Python, do not allow hyphens in their method signatures, AIO Tests allows case keys with underscores as valid mapping. The AIO Test key can be used in the method name by replacing the hyphen with underscores. eg. if AT-TC-123 is being automated by a test, the test method can be named as
verifyNotNullType_AT_TC_123
and the results of this method will be marked against AT-TC-123.Automation Key: The mapping of an AIO Case to an automated JUnit case can happen through a field Automation Key, which can be specified in the Case in AIO Tests app as shown below. The automation key is the fully qualified name of the test method i.e packagename.classname.methodname.
This can be useful at places where you do not want to add AIO case keys in the name or annotations or where automation is happening first without a manual case being created in AIO Tests.New Case creation: If no case key (e.g. SCRUM-TC-xx) or automation key is found with existing cases, a new case is created with
- title as thename
value from <testcase> tag of the JUnit report
- automation key asclassname.name
from the JUnit report.
- status as Published
- automation status as Automated
- automation owner as user uploading the resultsThe following flow summarizes the logic of JUnit case mapping when a key is not found via @DisplayName and via Automation key
Examples
Below are few examples that show results on testing the ForestCreator.java class.
Mapping using JUnit5 @DisplayName (when settings are done as shown above for DisplayName in SureFire/ANT task)
Add case key to Display name
Output: On import of the above report in AIO Tests, SCRUM-TC-2309 is updated. If case doesn’t exist then an appropriate error would be thrown
Mapping one automated case with multiple manual cases with JUnit5 @DisplayName
Add all case keys as part of Display name
Output: On import of the above report in AIO Tests, 3 cases are updated with result of the above execution → SCRUM-TC-2307, SCRUM-TC-2308 and SCRUM-TC-2350
. If case doesn’t exist then an appropriate error would be thrown
Mapping JUnit 4 case to existing manual case(s)
Method name can contain case key with underscores : plantTree_should_returnNumberOfTrees_AT_TC_222.
. OR
Automation Owner would have to mark the automated key value in an existing case to com.aio.tests.junit4.ForestCreatorTests.plantTree_should_returnNumberOfTrees
If single automated JUnit case needs to update multiple cases, then the automated key needs to be updated in multiple AIO Tests automation key values
Output: On import of the above report in AIO Tests, the automation key with com.aio.tests.junit4.ForestCreatorTests.plantTree_should_returnNumberOfTrees
would be searched for and the cases marked with this key would be added to cycle and updated
Parametrized Named Cases Convention
With the release of the data driven feature, it is now possible to create cases with datasets from JUnit cases.
The convention for creating data parameters with names is (params: parameterName1={0}, parameterName2={1}, parameterName1={2})
eg.
(params: userType={0},profile={1},income={2})
. This example would create a case with 3 data parameters : userType, profile and income and create datasets based on the Junit source values
The below example would create a testcase with 5 datasets
and a data parameter named month
A new flag has been introduced updateDatassets. This flag controls, whether the change in datasets should be used to update the Junit datasets case or not. The value can be set to false, when a subset of datasets are being run to avoid removal of datasets. If set to true, this flag affects only existing datasets cases.
Parametrized Non-Named Cases
If the name is not specified, and a default report is generated, AIO Tests generates new parameter names for JUnit 5 reports, which elaborate on user data. However, in Junit 4, in the absence of data in the report, cases would continue to work as individual cases.
In below case, AIO Tests would create a parameter named Parameter 1 and would create 5 datasets with the numbers [1, 3, 5, -3 and 15] as values.
Output : The case with automation key of com.aio.tests.ParametrizedRunNonNamedTest.plantTree
would be updated - 3 runs would be created with 1st and 3rd run showing pass and 2nd run showing Failed status
Importing Results
Post execution of a JUnit suite, the TEST-<xxx>.xml file can be uploaded either via
AIO Tests REST API call using multipart form-data to upload file
Please follow the above links to continue to import results using either of the options.
