## Testing

### Node

<details>
	<summary>(click to show)</summary>

`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 avaialble with `make test_misc`

```bash
$ make test_misc   # run core tests
$ make test        # run full tests
$ make test_xls    # only use the XLS test files
$ make test_xlsx   # only use the XLSX test files
$ make test_xlsb   # only use the XLSB test files
$ make test_xml    # only use the XML test files
$ make test_ods    # only use the ODS test files
```

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 flow        # make lint + Flow checking
```

### Browser

<details>
	<summary>(click to show)</summary>

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.

To run the full in-browser tests, clone the repo for
[oss.sheetjs.com](https://github.com/SheetJS/SheetJS.github.io) and replace
the xlsx.js file (then fire up the browser and go to `stress.html`):

```bash
$ cp xlsx.js ../SheetJS.github.io
$ cd ../SheetJS.github.io
$ simplehttpserver # or "python -mSimpleHTTPServer" or "serve"
$ open -a Chromium.app http://localhost:8000/stress.html
```

### 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)
