# Testing
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
`make test` will run the node-based tests. By default it runs tests on files in
every supported format. To test a specific file type, set `FMTS` to the format
you want to test. Feature-specific tests are available with `make test_misc`
```bash
$ make test_misc # run core tests
$ make test # run full tests
```
To enable all errors, set the environment variable `WTF=1`:
```bash
$ make test # run full tests
$ WTF=1 make test # enable all error messages
```
`flow` and `eslint` checks are available:
```bash
$ make lint # eslint checks
$ make tslint # check TS definitions
```
The core in-browser tests are available at `tests/index.html` within this repo.
Start a local server and navigate to that directory to run the tests.
`make ctestserv` will start a server on port 8000.
`make ctest` will generate the browser fixtures. To add more files, edit the
`tests/fixtures.lst` file and add the paths.
`make test-bun` will run the full Bun test suite and `make test-bun_misc`
will run the smaller feature-specific tests.
`make test-deno` will run the full Deno test suite and `make test-deno_misc`
will run the smaller feature-specific tests.
`make dist` will build `xlsx.extendscript.js`.
The script `estk.jsx` at the root of the project is configured to run in
ExtendScript Toolkit. It will read `sheetjs.xlsx` and attempt to write test
files in a number of file formats.
ExtendScript Toolkit 3.5 is available as a standalone download for Windows.

The test suite also includes tests for various time zones. To change
the timezone locally, set the `TZ` environment variable:
```bash
$ env TZ="Asia/Kolkata" WTF=1 make test_misc
```
### Test Files
Test files are housed in [another repo](https://github.com/SheetJS/test_files).
Running `make init` will refresh the `test_files` submodule and get the files.
Note that this requires `svn`, `git`, `hg` and other commands that may not be
available. If `make init` fails, please download the latest version of the test
files snapshot from [the repo](https://github.com/SheetJS/test_files/releases)
