[SUREFIRE-2010] Parameterized Selection Does not Work

**[David Georg Reichelt](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=dagere1989)** opened **[SUREFIRE-2010](https://issues.apache.org/jira/browse/SUREFIRE-2010?redirect=false)** and commented

In the current version (and also M6-SNAPSHOT), maven surefire is not capable of selecting parameterized tests based on the index. In https://maven.apache.org/surefire/maven-surefire-plugin/examples/single-test.html, it is described that this should work by providing the index, e.g. using 

```java
-Dtest=MyTest#method[$INDEX]
```

 or 

```java
-Dtest=MyTest#method[*]
```

 for all.

 

This happens both for JUnit 4 and JUnit 5.

I created a mwe demonstrating this problem: https://github.com/DaGeRe/parameterized-selection-demo

As far as I see it, the TestMethodFilter in  https://github.com/apache/maven-surefire/blob/master/surefire-providers/surefire-junit-platform/src/main/java/org/apache/maven/surefire/junitplatform/TestMethodFilter.java#L45 does the filtering, but has only a descriptor in the form:

 

```java
[engine:junit-jupiter]/[class:de.dagere.peass.ExampleTest]/[test-template:test(int)]
```

 

So there is not the concrete value, but only the information that an int should be provided. Therefore, I currently see not any option to fix this easily or get this running using a regex pattern.

Do I oversee something, or is it planned to fix this? If not, it would be better to update the documentation site accordingly.

Reproduce the parameterized selection cases from the linked demonstration project, then inspect surefire-providers/surefire-junit-platform/src/main/java/org/apache/maven/surefire/junitplatform/TestMethodFilter.java, especially the filtering described near line 45. Compare JUnit 4 and JUnit 5 behavior; done means index and wildcard selections work as documented, or the single-test documentation is corrected if they cannot be supported.
