Test262-Integrator
Integrates any project the test262-stream API with any ES host execution applying filters from a JS object.
Install
npm install --save-dev test262-integrator
Usage
const Integrator = require('test262-integrator');
Integrator({
testDir, // String: the path where Test262 is located.
execute, // (Async/Sync) Function: this function is called for
// every non-skipped test file, the return should be a
// result object.
filters, // (Optional) Object: a list of filters, see 'test/filters.yml'
// for an example.
paths: ['test/built-ins/Array/from'] // (Optional) Array of Strings:
// specifies exclusive paths to
// run the test.
verbose: // (Optional) Boolean: toggles a verbose mode for files
// execution (experimental).
}).then(results => {
// `results` is an Array of objects. Each object contains all
// relevant information for a given test produced by the test stream, with
// an additional `result` property which contains the results of
// the execution. If a test was skipped via filtering parameters, the
// value of result property is { skip: true }.
// Anything returned from the `execute` method will be stored in the
// result property.
}, err => {
// Any execution error will be available here
});
// The execute function signature:
function execute(test) {
// `test` has the same properties used in test262-stream*
// This function can return a promise for async operations.
}
Filters
The filters
object can include any properties known to Test262, as well as a special paths
property whose value is an array of string paths relative to test262
. All test file paths that match entries in paths
will be skipped.
All tests that are matched by the filter object will have a property results
whose value is { skip: true }
.
Test262-Integrator recommends using a YAML file to store filters, as it's the most readable and maintainable format.
Examples
(See test/filters.yml for an extensive example)
YAML Filter File
features:
- tail-call-optimization
- generators
- default-parameters
JSON Filter File
{
"features": [
"tail-call-optimization",
"generators",
"default-parameters"
]
}
JavaScript Object Filter
const filters = {
features: [
'tail-call-optimization',
'generators',
'default-parameters'
]
};
More Extensive Example
const filters = {
// Filters by metadata:
features: [
'tail-call-optimization',
'SharedArrayBuffer',
],
esid: ['pending'],
es5id: ['15.1.2.2_A8', '15.1.2.3_A6'],
es6id: ['22.1.3.1_3'],
flags: ['module', 'async'],
// Filters by path location:
paths: [
// filters will apply to any match, as long as the path contains the string from any index.
// In this example, any file path containing `harness` will be skipped.
'harness',
'intl402',
'built-ins/Function/prototype/toString/',
'built-ins/SharedArrayBuffer/',
'built-ins/Atomics/',
'annexB/',
],
// Filter negative tests by any matching phases and type
negative: {
type: ['SyntaxError'],
phase: [
'early',
'runtime',
],
},
