find-test-names-tags
Given a Mocha / Cypress spec file, returns the list of suite and test names
Install
# install using NPM, probably as a dev dependency
$ npm i -D find-test-names-tags
# install using Yarn
$ yarn add -D find-test-names-tags
Use
const { getTestNames } = require('find-test-names-tags')
const result = getTestNames(specSourceCode)
// { "suiteNames": [], "testNames": [], "tests": [] }
The tests
is a list with each test and suite name, and optional list of tags.
// spec.js
it(['@user'],'works', () => { ... })
// found test names
// { tests: [{ name: 'works', tags: ['@user'] }] }
withStructure
You can get the entire structure of suites and tests by passing true
argument
const result = getTestNames(specSourceCode, true)
// use the result.structure array
To view this in action, use npm run demo-structure
which points at bin/find-tests.js
Pending tests
The tests it.skip
are extracted and have the property pending: true
setEffectiveTags
Often, you want to have each test and see which tags it has and what parent tags apply to it. You can compute for each test a list of effective tags and set it for each test.
// example spec code
describe(['@user'],'parent', () => {
describe(['@auth'],'parent', () => {
it(['@one'],'works a', () => {})
it(['@one', '@two']'works b', () => {})
})
})
const { getTestNames, setEffectiveTags } = require('find-test-names-tags')
const result = getTestNames(source, true)
setEffectiveTags(result.structure)
If you traverse the result.structure
, the test "works a" will have the effectiveTags
list with @user, @auth, @one
, and the test "works b" will have the effectiveTags
list with @user, @auth, @one
.
filterByEffectiveTags
Once you setEffectiveTags
, you can filter all tests by an effective tag. For example, to fid all tests with the given tag(@one) and without other tags(@two):
const {
getTestNames,
setEffectiveTags,
filterByEffectiveTags,
} = require('find-test-names-tags')
const result = getTestNames(source, true)
setEffectiveTags(result.structure)
const tests = filterByEffectiveTags(result.structure, ['@one'], ['@two'])
Returns individual test objects.
Tip: you can pass the source code and the tags to the filterByEffectiveTags
function and let it parse it
const filtered = filterByEffectiveTags(source, ['@user'], ['@two'])
findEffectiveTestTags
Returns a single object with full test titles as keys. For each key, the value is the list of effective tags. See the find-effective-tags.js spec file.
findEffectiveTestTagsIn
You can use the utility method findEffectiveTestTagsIn(filename)
to let this module read the file from disk and find the effective tags that apply to each test by its full title.
Bin
This package includes bin/find-test-names.js that you can use from the command line
$ npx find-test-names <path to the spec file>
# prints the describe and test names found in the spec file
print-tests
Print found suites an tests
$ npx print-tests <spec pattern>
For example, in this repo
$ npx print-tests 'test-cy/**/*.js'
test-cy/spec-a.js
└─ Suite A
├─ works 1
└─ works 2
test-cy/spec-b.js
└─ Suite B
├─ works 1
└─ works 2
Pending tests and suites are marked with ⊙
character like this:
├─ first
├⊙ second
└⊙ last
If there are tags, they are shown after the name
├─ first [tag1, tag2]
├─ second [@sanity]
└─ last
Unknown test names
Sometimes a test name comes from a variable, not from a literal string.
// test name is a variable, not a literal string
const testName = 'nice'
it(testName, () => {})
In that case, the tags are still extracted. When printing, such tests have name <unknown test>
.
comment lines
If the test function has preceding comment lines, the comment line right before the test is extracted and included
// line 1
// line 2
// line 3
it('works', ...)
// extracted test object will have
// name: "works",
// comment: "line 3"
Debugging
Run with the environment variable DEBUG=find-test-names-tags
to see verbose logs
