This PR moves the puppeteer source code into separate mono-repo packages: - `puppeteer` and `puppeteer-core` are now separated into their own packages. - `puppeteer-core` has a new exports called `puppeteer-core/internal` for internal usage. Tests and various tools have been updated to accommodate the migration.

# Mocha Runner
|
|
|
|
Mocha Runner is a test runner on top of mocha. It uses `/test/TestSuites.json` and `/test/TestExpectations.json` files to run mocha tests in multiple configurations and interpret results.
|
|
|
|
## Running tests for Mocha Runner itself.
|
|
|
|
```
|
|
npm run build:test && npx c8 node utils/mochaRunner/lib/test.js
|
|
```
|
|
|
|
## Running tests using Mocha Runner
|
|
|
|
```
|
|
npm run build:test && npm run test
|
|
```
|
|
|
|
By default, the runner runs all test suites applicable to the current platform.
|
|
To pick a test suite, provide the `--test-suite` arguments. For example,
|
|
|
|
```
|
|
npm run build:test && npm run test -- --test-suite chrome-headless
|
|
```
|
|
|
|
## TestSuites.json
|
|
|
|
Define test suites via the `testSuites` attribute. `parameters` can be used in the `TestExpectations.json` to disable tests
|
|
based on parameters. The meaning for parameters is defined in `parameterDefinitons` which tell what env object corresponds
|
|
to the given parameter.
|
|
|
|
## TestExpectations.json
|
|
|
|
An expectation looks like this:
|
|
|
|
```
|
|
{
|
|
"testIdPattern": "[accessibility.spec]",
|
|
"platforms": ["darwin", "win32", "linux"],
|
|
"parameters": ["firefox"],
|
|
"expectations": ["SKIP"]
|
|
}
|
|
```
|
|
|
|
`testIdPattern` defines a string that will be used to prefix-match tests. `platforms` defines the platforms the expectation is for (`or`-logic).
|
|
`parameters` defines the parameters that the test has to match (`and`-logic). `expectations` is the list of test results that are considered to be acceptable.
|
|
|
|
Currently, expectations are updated manually. The test runner outputs the suggested changes to the expectation file if the test run does not match
|
|
expectations.
