# Tools for Node.js compatibility work
|
|
|
|
We run
|
|
[native Node.js test cases](https://github.com/nodejs/node/tree/main/test)
|
|
against our Node.js compatibility feature.
|
|
|
|
This directory includes the tools for downloading, setting up, and updating the
|
|
Node.js compat testing in Deno repository.
|
|
|
|
- `//tools/node_compat/setup.ts`
|
|
- This script sets up the Node.js compat tests.
|
|
- `//tools/node_comapt/versions/`
|
|
- Node.js source tarballs and extracted test cases are stored here.
|
|
- `//cli/tests/node_compat/config.json`
|
|
- This json file stores the settings about which Node.js compat test to run
|
|
with Deno.
|
|
- `//cli/tests/node_compat/test`
|
|
- The actual test cases are stored here.
|
|
|
|
## Steps to add new test cases from Node.js test cases
|
|
|
|
1. Update `tests` property of `//cli/tests/node_compat/config.json`. For
|
|
example, if you want to add `test/paralles/test-foo.js` from Node.js test
|
|
cases, then add `test-foo.js` entry in `tests.parallel` array property in
|
|
`config.json`
|
|
1. Run `./tools/node_compat/setup.ts`
|
|
|
|
The above command copies the updated items from Node.js tarball to the Deno
|
|
source tree.
|
|
|
|
Ideally Deno should pass the Node.js compat tests without modification, but if
|
|
you need to modify it, then add that item in `ignore` perperty of `config.json`.
|
|
Then `setup.ts` doesn't overwrite the modified Node.js test cases anymore.
|
|
|
|
If the test needs to be ignored in particular platform, then add them in
|
|
`${platform}Ignore` property of `config.json`
|
|
|
|
## Run Node.js test cases
|
|
|
|
Node.js compat tests are run as part of `cargo test` command. If you want to run
|
|
only the Node.js compat test cases you can use the command
|
|
`cargo test node_compat`.
