Question

How could trial output be converted to JUnit xml format? There is no such possible report format in trial.

$> trial --help-reporters
Trial's output can be customized using plugins called Reporters. You can
select any of the following reporters using --reporter=<foo>

    subunit     subunit output
    bwverbose   Colorless verbose output
    text    terse text output
    verbose     verbose color output (default reporter)
    timing  Timing output
    summary     minimal summary output

Answer 1

The simplest way to do it is by setting the reporter of trial to be subunit and then convert the output to JUnit via the subunit2junitxml found in subunit (under the filters folder in trunk).

For example we do:

trial --reporter=subunit | subunit2junitxml --forward --output-to=junitxml-result.xml
