Commas in arrays printed as \u002C on console #337

Closed GoogleCodeExporter closed 8 years ago

What steps will reproduce the problem? If possible, provide source code and 
stack trace.
1. Create a Spock test and use an array (e.g. args of a main method) as a 
parameter in @Unroll
2. Run tests from an IDE like IntelliJ IDEA: Everything is fine, the test name 
shows up correctly including the expanded parameter
3. Run the same tests from a console, e.g. from Maven. All commas separating 
array elements in the test's name/caption are shown as "\u002C"

What version of Spock and Groovy are you using?

Maven 3 configuration:

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

Please provide any additional information below. You can also assign
labels.

Sample Maven output:

Failed tests:   Calculation [-customer\u002C -1111](OrderGeneratorTest): 
Unexpected call of System.exit(1).

Tests in error:
  Calculation [-customer\u002C -1111](OrderGeneratorTest): Tried to exit with status 1.

Actually the expected output is:

Failed tests:   Calculation [-customer, -1111](OrderGeneratorTest): Unexpected 
call of System.exit(1).

Tests in error:
  Calculation [-customer, -1111](OrderGeneratorTest): Tried to exit with status 1.

Not sure what the problem is, but it doesn't sound like a problem on Spock's 
side. Maybe your build or terminal has the wrong character encoding set.

What do you need to be sure? I work on Win7 Pro, German edition. The problem 
appears with Maven on all four consoles tested: Git Bash, cmd.exe, Cygwin Bash, 
IntelliJ IDEA internal console output. Actually there should be some way to 
specify the encoding on Maven, maybe as a config parameter of the spock 
dependency or the gmaven plugin.

No, sorry, my mistake. Win7 Pro in English edition, not German. I tested at 
work, not at home, my mistake.

I am sure because Spock doesn't get to choose any encoding. (It's not even 
responsible for printing the message to standard out.) I'm not sure it's an 
encoding problem, because that normally manifests differently. Nevertheless, 
I'd check the encoding used by the JVM that's running the tests 
(`file.encoding` system property), and the encoding used by your terminal.

So now you are sure? I asked because earlier you wrote:

> Not sure what the problem is

Anyway, on all 4 consoles mentioned earlier all other types of output - and 
Maven as well as the Java program itself produce a lot of them during testing - 
are perfectly okay, i.e. commas and other special characters are printed 
exactly the right way. I do not say it is Spock's fault. I am not looking for 
culprits, just for a root cause and a way to fix it. I figured you know more 
about your own tool than I do. Are you not interested in helping to fix 
problems in Maven-driven projects, even though they might just affect you 
indirectly? The "wasn't me" attitude helps nobody.

I'm not sure what the problem is, but I'm sure that it's not a problem on 
Spock's side. That's a very important statement, because it allows you to 
search for a cause in other places. I've already tried to help and provided 
concrete directions. The nature of the problem isn't at all specific to Spock, 
and I can't investigate your environment, so it's your job to find the cause 
for this. Good luck.

PS: If you want someone else to have a closer look at your problem, a minimal 
self-contained reproducible example helps tremendously. It also allows you to 
run the example in other environments and check whether the problem exists 
there too.

More info: It happens both on Windows with Cp1252 and on Linux with UTF-8 on 
the console. It is definitely a problem in decoding the output of Spock, 
probably caused by some Maven plugin. Proof:

If you want to reproduce it, just clone 
https://github.com/kriegaex/order-generator.git, then break one of the test 
cases in order to provoke the test failure output for Spock.

I think this JUnit add-on produces the erroneous output:

        <dependency>
            <!-- JUnit 4.7+ rule ExpectedSystemExit for handling System.exit() in tests -->
            <groupId>com.github.stefanbirkner</groupId>

            <version>1.3.1</version>
            <scope>test</scope>
        </dependency>

I am going to contact the author. Thanks for your help thus far.

The bug was caused by this bug in Maven Surefire Plugin: 
http://jira.codehaus.org/browse/SUREFIRE-857

The default in Maven 3.1.1 is Surefire 2.12.4 which is fine. But with Maven 
3.0.5 the plugin version is 2.10 as can be seen in the effective POM. So the 
solution is to explicitly use a Surefire plugin version >= 2.12.3.
