---------------------------------------
Summary: Surefire report for JUnit5 DynamicContainer/DynamicTest
doesn't work with HTML generation
Key: SUREFIRE-2147
URL: https://issues.apache.org/jira/browse/SUREFIRE-2147
Project: Maven Surefire
Issue Type: Bug
Reporter: Geoff Soutter
I created a really simple example of JUnit5 DynamicContainer/DynamicTest
{code}
package samplepackage;
...
public class SampleTest {
@TestFactory
Collection<DynamicContainer> createDynamicTests() {
List<DynamicTest> testList = new ArrayList<>();
testList.add(DynamicTest.dynamicTest("test1", new MyExecutable()));
testList.add(DynamicTest.dynamicTest("test2", new MyExecutable()));
List<DynamicContainer> root = new ArrayList<>();
root.add(DynamicContainer.dynamicContainer("aFolder", testList));
return root;
}
private static class MyExecutable implements Executable {
@Override
public void execute() throws Throwable {
}
}
}
{code}
When I run this in IDEA. I get the following structure
* SampleTest
** createDynamicTests()
*** aFolder
**** test1
**** test2
Here we can see that dynamic tests are represented by IDEA as nested children
of the test method. We can open and close the "virtual packages" created as
usual to explore in the dynamically created test results. It is not a "flat
list".
Using surefire 3.0.0-m7, it creates contents in surefire-reports like so:
{code}
<testcase name="aFolder createDynamicTests() test1"
classname="samplepackage.SampleTest" time="0.02"/>
<testcase name="aFolder createDynamicTests() test2"
classname="samplepackage.SampleTest" time="0.001"/>
{code}
Here all the nested synthetic tests are created as the child of a single class
in the HTML report. The folder name is injected into the "method" name. That
is, from a reporting perspective, they are created as a flat list.
This doesn't scale nicely as the number of tests in the dynamically created
"folder" structure grows. We can't view the different DynamicContainers
separately in the rendered HTML reports. We can't get history on any particular
DynamicContainer in the rendered HTML reports.
I think what we want here is that dynamic tests in folders should have those
folders structured as synthetic packages. This allows us the benefits of having
the nested structure modelled correctly in the HTML report. I think we could do
that by moving the method name and folder name from name= into classname=
<testcase name="test1"
classname="samplepackage.SampleTest.createDynamicTests().aFolder.Test"
time="0.02"/>
<testcase name="test2" classname="samplepackage.SampleTest.aFolder
createDynamicTests().Test" time="0.001"/>
A compromise I have made here is that I have injected .Test at the end as it
allows the entire DynamicContainer "folder" structure to be visible in the
virtual package name - DynamicTests don't have a "class" concept.
