Test failing unexpected

[g-bohncke]

While running any test via the maven plugin I get them failing with:

Running Test [example] for Flow [sayHello] from Suite [Testsuite_1]

Test case example doesnt have any assertions. Test execution skipped.
Running Test [greg] for Flow [sayHello] from Suite [Testsuite_1]

Test case greg doesnt have any assertions. Test execution skipped.
Running Test [weird chars] for Flow [sayHello] from Suite [Testsuite_1]

Test case weird chars doesnt have any assertions. Test execution skipped.

while if I run the same tests in vscode or via cli they pass:
./target/HelloWorld.exe test --test-file ./example.flogotest --app ./example.flogo --result-filename example.testresult --collect-coverage --test-preserve-io

Test case greg execution completed. All assertions passed

I think it has to do with the default value of the --test-preserve-io flag if i omit it from the cli call it also starts failing.

    @Parameter(property = "saveActivityInputOutput", defaultValue = "false")
    private boolean preserveIO;
