A jest reporter that generates junit xml files
npm install jest-junit
Note: as of jest-junit 11.0.0 NodeJS >= 10.12.0 is required.
shell
yarn add --dev jest-junit
`Usage
In your jest config add the following entry:
JSON
{
"reporters": [ "default", "jest-junit" ]
}
`Then simply run:
shell
jest
`For your Continuous Integration you can simply do:
shell
jest --ci --reporters=default --reporters=jest-junit
`Usage as testResultsProcessor (deprecated)
The support for is only kept for [legacy reasons][test-results-processor] and might be removed in the future.
You should therefore prefer to configure jest-junit as a _reporter_.Should you still want to, add the following entry to your jest config:
`JSON
{
"testResultsProcessor": "jest-junit"
}
`Then simply run:
shell
jest
`For your Continuous Integration you can simply do:
shell
jest --ci --testResultsProcessor="jest-junit"
`Configuration
offers several configurations based on environment variables or a jest-junit key defined in package.json or a reporter option.
Environment variable and package.json configuration should be strings.
Reporter options should also be strings exception for suiteNameTemplate, classNameTemplate, titleNameTemplate that can also accept a function returning a string.| Environment Variable Name | Reporter Config Name| Description | Default | Possible Injection Values
|---|---|---|---|---|
|
JEST_SUITE_NAME | suiteName | name attribute of | "jest tests" | N/A
| JEST_JUNIT_OUTPUT_DIR | outputDirectory | Directory to save the output. Relative path outside of project root (e.g. in monorepos) has to be prefixed with literal, e.g. | process.cwd() | N/A
| JEST_JUNIT_OUTPUT_NAME | outputName | File name for the output. | "junit.xml" | N/A
| JEST_JUNIT_OUTPUT_FILE | outputFile | Fullpath for the output. If defined, outputDirectory and outputName will be overridden | undefined | N/A
| JEST_JUNIT_UNIQUE_OUTPUT_NAME | uniqueOutputName | Create unique file name for the output leveraging the outputName as a prefix if given ${outputName}-${uuid}.xml or a default of junit-${uuid}.xml if outputName is not specified, overrides outputName | false | N/A
| JEST_JUNIT_SUITE_NAME | suiteNameTemplate | Template string for name attribute of the . | "{title}" | {title}, {filepath}, {filename}, {displayName}
| | classNameTemplate | Template string for the classname attribute of . | "{classname} {title}" | {classname}, {title}, {suitename}, {filepath}, {filename}, {displayName}
| | titleTemplate | Template string for the name attribute of . | "{classname} {title}" | {classname}, {title}, {filepath}, {filename}, {displayName}
| | ancestorSeparator | Character(s) used to join the describe blocks. | " " | N/A
| JEST_JUNIT_ADD_FILE_ATTRIBUTE | addFileAttribute | Add file attribute to the output (validated on CIRCLE CI and GitLab CI). Must be a string. | "false" | N/A
| JEST_JUNIT_FILE_PATH_PREFIX | filePathPrefix | Prefix to add to the test suite file path. The value will be prefixed using path.join. Useful in case of monorepo | "" | N/A
| JEST_JUNIT_INCLUDE_CONSOLE_OUTPUT | includeConsoleOutput | Adds console output to any testSuite that generates stdout during a test run. | false | N/A
| JEST_JUNIT_INCLUDE_SHORT_CONSOLE_OUTPUT | includeShortConsoleOutput | Adds short console output (only message value) to any testSuite that generates stdout during a test run. | false | N/A
| JEST_JUNIT_REPORT_TEST_SUITE_ERRORS | reportTestSuiteErrors | Reports test suites that failed to execute altogether as error. _Note:_ since the suite name cannot be determined from files that fail to load, it will default to file path.| false | N/A
| JEST_JUNIT_NO_STACK_TRACE | noStackTrace | Omit stack traces from test failure reports, similar to jest --noStackTrace | false | N/A
| JEST_USE_PATH_FOR_SUITE_NAME | usePathForSuiteName | DEPRECATED. Use suiteNameTemplate instead. Use file path as the name attribute of | "false" | N/A
| JEST_JUNIT_TEST_CASE_PROPERTIES_JSON_FILE | testCasePropertiesFile | Name of the custom testcase properties file | "junitProperties.js" | N/A
| JEST_JUNIT_TEST_CASE_PROPERTIES_DIR | testCasePropertiesDirectory | Location of the custom testcase properties file | process.cwd() | N/A
| JEST_JUNIT_TEST_SUITE_PROPERTIES_JSON_FILE | testSuitePropertiesFile | Name of the custom testsuite properties file | "junitTestCaseProperties.js" | N/A
| JEST_JUNIT_TEST_SUITE_PROPERTIES_DIR | testSuitePropertiesDirectory | Location of the custom testsuite properties file | process.cwd() | N/A
You can configure these options via the command line as seen below:
`shell
JEST_SUITE_NAME="Jest JUnit Unit Tests" JEST_JUNIT_OUTPUT_DIR="./artifacts" jest
`Or you can also define a
key in your package.json. All are string values.`
{
...
"jest-junit": {
"suiteName": "jest tests",
"outputDirectory": ".",
"outputName": "junit.xml",
"uniqueOutputName": "false",
"classNameTemplate": "{classname}-{title}",
"titleTemplate": "{classname}-{title}",
"ancestorSeparator": " › ",
"usePathForSuiteName": "true"
}
}
Or you can define your options in your reporter configuration.
js
// jest.config.js
{
reporters: [
"default",
[ "jest-junit", { suiteName: "jest tests" } ]
]
}
`

If using the and suiteNameTemplate, the usePathForSuiteName value will take precedence. ie: if usePathForSuiteName=true and suiteNameTemplate="{filename}", the filepath will be used as the name attribute of the in the rendered jest-junit.xml).$3
Below are some example configuration values and the rendered
.xml to created by jest-junit.The following test defined in the file
/__tests__/addition.test.js will be used for all examples:
`js
describe('addition', () => {
describe('positive numbers', () => {
it('should add up', () => {
expect(1 + 2).toBe(3);
});
});
});
`#### Example 1
The default output:
xml
`#### Example 2
Using the
and titleTemplate:`shell
JEST_JUNIT_CLASSNAME="{classname}" JEST_JUNIT_TITLE="{title}" jest
`renders
xml
`#### Example 3
Using the
:`shell
JEST_JUNIT_ANCESTOR_SEPARATOR=" › " jest
`
rendersxml
`#### Example 4
Using the
:`shell
JEST_JUNIT_SUITE_NAME ="{filename}" jest
`xml
`
#### Example 5
Using
as a function in reporter options`js
// jest.config.js
{
reporters: [
"default",
[
"jest-junit",
{
classNameTemplate: (vars) => {
return vars.classname.toUpperCase();
}
}
]
]
}
`renders
xml
`#### Adding custom testsuite properties
New feature as of jest-junit 11.0.0!
Create a file in your project root directory named junitProperties.js:
js
module.exports = () => {
return {
key: "value",
};
};
`Will render
xml
`#### Adding custom testcase properties
Create a file in your project root directory named junitTestCaseProperties.js:
js
module.exports = (testResult) => {
return {
"dd_tags[test.invocations]": testResult.invocations,
};
};
`Will render
xml
`WARNING: Properties for testcases is not following standard JUnit XML schema.
However, other consumers may support properties for testcases like DataDog metadata through
