Allow to use in combination with other assertion frameworks

[jotak]

It would be nice to use VertxUnit in combination with other assertion frameworks, such as assertj.

As I understand, it essentially means that async "completeness" must be handled on assertion errors.

So I suggest to add a method in TestContext such as void run(Runnable r) that takes any piece of code (which may contain assertions using another assertion framework), catches AssertionError and use the TestContext fail method.

PS: I'm writing a PR

[vietj]

can you take inspiration from vertx-junit 5 that provides a new verify method on VertxTestContext ? it would be good to have the same API in both project.

[jotak]

Indeed it looks exactly the same as what I'm writing, except the method name, so I'll call it verify as well.

@vietj , Runnable is not allowed? It's used in the junit5 module, but in vertx-unit I get:

[ERROR] diagnostic: /work/vertx-unit/src/main/java/io/vertx/ext/unit/TestContext.java:212: error: Could not generate model for io.vertx.ext.unit.TestContext#verify(java.lang.Runnable): type java.lang.Runnable is not legal for use for a parameter in code generation
  TestContext verify(Runnable block);

(I could use Handler<Void> , but it would have an unused parameter)

[vietj]

Handler is the polyglot way to go

[vietj]

so it's fine
