JUnit test that uses ExpectIt fails when run by Ant
randy....@gmail.com
When I use Expect in my JUnit tests and run them with ant -- they fail miserably in the setUp() (@before) methods.
Here is the body of my setUp() method (as I said, it works using the junit runner):
ProcessBuilder pb = new ProcessBuilder("python","-u", "tictactoe.py");
process = pb.start();
expect = new ExpectBuilder()
.withTimeout(1000, TimeUnit.MILLISECONDS)
.withInputs(process.getInputStream(), process.getErrorStream())
.withOutput(process.getOutputStream())
.build();
StringBuilder sb = new StringBuilder();
sb.append("This is the current board: " + System.lineSeparator());
sb.append("[[0, 0, 0]," + System.lineSeparator());
sb.append(" [0, 0, 0]," + System.lineSeparator());
sb.append(" [0, 0, 0]]" + System.lineSeparator());
sb.append("Choose where to play. Enter two numbers seperated by a comma, for example: 1,1 ");
initString = sb.toString();
try{
boolean result = expect.expect(exact(initString)).isSuccessful();
assertTrue(result);
} catch (IOException e) {
fail(ExceptionUtils.getStackTrace(e));
}
Here is my ant JUnit target:
<target name="test" depends="test-compile">
<junit printsummary="on" haltonfailure="no">
<classpath>
<path refid="classpath.test"/>
<pathelement location="${test.build.dir}"/>
</classpath>
<formatter type="xml" />
<formatter type="plain" />
<batchtest>
<fileset dir="${test.src.dir}" includes="*Tests.java" />
</batchtest>
</junit>
</target>
Here is the exception:

It seems as though ant is closing the streams in my setUp() method for some reason. Any hints as to how to modify my ant JUnit target so it won't do that?
fork true false on off doesn't help.
