Add options to print stack trace / stdout / stderr on error or failure

[blutorange]

I just found this extension and it is great! Makes test output much more readable. One thing I did miss, however, is the ability to see console output and stack traces when a test fails. This commit

• adds some options to print the strack trace and stdout / stderr depending on whether a test fails or succeeds
• also adds a <theme>ASCII</code> or <theme>UNICODE</theme> option and deprecates JUnit5StatelessTestsetInfoTreeReporterUnicode in favor of that option. If we have multiple options, the theme might as well be an option as well.

From the readme:

By default, <consoleOutputReporter><disable>true</disable></consoleOutputReporter> disables all console output. To debug test failures, it may be useful to see the console output and stack traces when a test fails. To do so, you can configure this extension like this:

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M7</version>
    <dependencies>
        <dependency>
            <groupId>me.fabriciorby</groupId>
            <artifactId>maven-surefire-junit5-tree-reporter</artifactId>
            <version>1.1.0</version>
        </dependency>
    </dependencies>
    <configuration>
        <reportFormat>plain</reportFormat>
        <consoleOutputReporter>
            <disable>true</disable>
        </consoleOutputReporter>
        <statelessTestsetInfoReporter
                implementation="org.apache.maven.plugin.surefire.extensions.junit5.JUnit5StatelessTestsetInfoTreeReporter">
            <printStacktrackeOnError>true</printStacktrackeOnError>
            <printStacktrackeOnFailure>true</printStacktrackeOnFailure>
            <printStdoutOnError>true</printStdoutOnError>
            <printStdoutOnFailure>true</printStdoutOnFailure>
            <printStdoutOnSuccess>false</printStdoutOnSuccess>
            <printStderrOnError>true</printStderrOnError>
            <printStderrOnFailure>true</printStderrOnFailure>
            <printStderrOnSuccess>false</printStderrOnSuccess>
            <theme>UNICODE</theme>
        </statelessTestsetInfoReporter>
    </configuration>
</plugin>

The options all default to false to preserve the current behavior. Although I think it would also help to print details for errors and failures by default.

The resulting output looks like this:

Hey! Really nice PR, thanks for that! I didn't know it was possible to get params from the XML like that! :)

I will merge to the develop branch for now, do some minor changes, and then we go master.

If I can help, let me know. This plugin is really useful, we've got integration tests that produce huge amounts of logging output. The log files from the CI run are now only a few MB instead of several dozen MB : )

I have just deployed the new version 1.2.0. :)
