better_test_reporter 0.1.0

A CLI for generating a junit xml report from dart test json output and libraries for parsing test json into dev-friendly models

Using report_to_junit to generate JUnit XML test results

Lets say you have a placeholder test file named placeholder_test.dart below:

import 'package:test/test.dart';
void main() {
  test('placeholder test', () {
    expect(true, isTrue);
  });
}

In order to run this test and get json output, you would run:

dart pub run test placeholder_test.dart --reporter json > test_output.json

As a note, if running flutter tests, you will need to use the --machine command line option to generate the json output rather than --reporter json like for dart tests.

Once the output is collected in test_output.json, you can then use report_to_junit to generate the JUnit XML

dart pub global run better_test_reporter:report_to_junit --input test_output.json --output test_report.xml

This will generate a test_report.xml that will look something like:

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
  <testsuite errors="0" failures="0" tests="1" skipped="0" name="placeholder" timestamp="2021-10-22T21:20:08">
    <properties>
      <property name="platform" value="vm"/>
    </properties>
    <testcase classname="placeholder" file="/test/placeholder_test.dart" name="placeholder test" time="0.02"/>
  </testsuite>
</testsuites>

Many continuous integration tools can utilize this JUnit XML output to better display the results of your tests.
