go-custom-junit-report

Create custom Junit XML reports in GO.

What is this package?

go-custom-junit-report allows you to create a custom XML in the jUnit format. This format is widely used by CI/CD tools like Gitlab and Bitbucket. While most of the time the report generation is built into your test framework, you may find yourself creating custom tests (like integration tests for example) and in need of generating your own results.

Supported jUnit format

Example:

<?xml version="1.0" encoding="UTF-8"?>
<testsuites id="testsuites#1" name="test_report" tests="4" failures="3" errors="3">
    <testsuite id="testsuite#1" name="suite 1" tests="2" failures="3" errors="3">
        <testcase id="case#1" name="case 1" classname="report.TestMakeReport"></testcase>
        <testcase id="case#2" name="case 2" classname="report.TestMakeReport">
            <failure message="msg1" type="type_fail">test failure 1</failure>
            <failure message="msg2" type="type_fail">test failure 2</failure>
            <failure message="msg3" type="type_fail">test failure 3</failure>
            <error message="msg4" type="type_err">test error 1</error>
            <error message="msg5" type="type_err">test error 2</error>
            <error message="msg6" type="type_err">test error 3</error>
        </testcase>
    </testsuite>
    <testsuite tests="2" failures="0" errors="0">
        <testcase></testcase>
        <testcase></testcase>
    </testsuite>
</testsuites>

XML Elements:

Test case elements are grouped into a test suite. Test suites elemnts are gouped in the test suites element.

Test suites element:

Name	Description	Optional	Observations
id	Test suites ID	Yes	Omitted when empty
name	Test suites name	Yes	Omitted when empty
tests	Total number of test cases	No	Defaults to 0
failures	Total number of failures	No	Defaults to 0
errors	Total number of errors	No	Defaults to 0
time	Total time	Yes	Omitted when empty

Test suite element:

Name	Description	Optional	Observations
id	Test suite ID	Yes	Omitted when empty
name	Test suite name	Yes	Omitted when empty
tests	Number of test cases	No	Defaults to 0
failures	Number of failures	No	Defaults to 0
errors	Number of errors	No	Defaults to 0
time	Suite time	Yes	Omitted when empty

Test case element:

Name	Description	Optional	Observations
id	Test suite ID	Yes	Omitted when empty
name	Test suite name	Yes	Omitted when empty
classname	Test suite class name	Yes	Omitted when empty
failures	Number of failures	No	Defaults to 0
errors	Number of errors	No	Defaults to 0
time	Test time	Yes	Omitted when empty

Each test case element can contain the test case output.

Failure element:

Name	Description	Optional	Observations
message	Failure message	Yes	Omitted when empty
type	Failure type	Yes	Omitted when empty

The failure element can contain the failure output.

Error element:

Name	Description	Optional	Observations
message	Error message	Yes	Omitted when empty
type	Error type	Yes	Omitted when empty

The error element can contain the failure output.

How to use it

    suites := NewTestSuites("id", "name")
    suite := NewTestSuite("id", "name")
    suites.AddTestSuite(suite)

    testCase := NewTestCase("id", "name", "classname")

    // start tracking test duration
    testCase.Start()

    // test code
    ok, err := testCode()

    // finish tracking test duration
    testCase.End()

    if !ok {
        failure := NewFailure("failure message", "failure type", "failure output")
        testCase.AddFailure(failure)
    } else {
        // optional: set test output
        testCase.SetContent("output")
    }

    if err != nil {
        testErr := NewError("error message", "error type", "error output")
        testCase.AddError(testErr)
    }

    suite.AddTestCase(testCase)

    suites.SaveReport("filename.xml")
