Invoke @BeforeAll method for a dry run

[wazzeps]

🤔 What's the problem you're trying to solve?

Currently, if the dry run property is set to true outside a method annotated with @BeforeAll, this method is not invoked.

Therefore, there is no possibility to dynamically filter scenarios in the code.

A dry run without filtering does not take much time, but it affects the overall statistics of automated tests, since third-party libraries cannot distinguish the result of a normal run from a dry one.

✨ What's your proposed solution?

Add a configuration property to enable/disable the @BeforeAll (and @ AfterAll ?) method invocation.

⛏ Have you considered any alternatives or workarounds?

For now we can set the dry run property to true in the @BeforeAll method and it will be invoked.

📚 Any additional context?

Could you clarify what you mean by dynamic filtering? I don't believe you that this is currently possible at all.

[wazzeps]

Calculating the filtering expression at runtime. At least it works with tags.

@BeforeAll
public static void beforeAll() {
    System.setProperty(Constants.EXECUTION_DRY_RUN_PROPERTY_NAME, String.valueOf(true));
    System.setProperty(Constants.FILTER_TAGS_PROPERTY_NAME, calculateTagsExpression());
}

But in case the dry run property is set to true, for example, in the Gradle task, this will not work, because the @BeforeAll method will not be invoked.

As you are using Gradle, and presumably the JUnit Platform, have you considered using the JUnit 5 tag expressions (slightly different from Cucumbers) and calculating these in Gradle?
