# Testing Text Processing The text processing tests located in the [doc/developer/tests folder](https://github.com/mattermost/platform/tree/master/doc/developer/tests) are designed for use with the `/test url` command. This command posts the raw contents of a specified .md file in the doc/developer/test folder into Mattermost. ## Turning on /test Access the **System Console** from the Main Menu. Under *Service Settings* make sure that *Enable Testing* is set to `true`, then click **Save**. You may also change this setting from `config.json` by setting `”EnableTesting”: true`. Changing this setting requires a server restart to take effect. ## Running the Tests In the text input box in Mattermost, type: `/test url [file-name-in-testing-folder].md`. Some examples: `/test url test-emoticons.md` `/test url test-links.md` #### Notes: 1. If a test has prerequisites, make sure your Mattermost setup meets the requirements described at the top of the test file. 2. Some tests are over 4000 characters in length and will render across multiple posts. ## Manual Testing It is possible to manually test specific sections of any test, instead of using the /test command. Do this by clicking **Raw** in the header for the file when it’s open in GitHub, then copy and paste any section into Mattermost to post it. Manual testing only supports sections of 4000 characters or less per post. ## Test plugins There are three test plugins: `testplugin.tar.gz`, `testplugin-v0.0.2.tar.gz`, and `testplugin2.tar.gz`. These are use in some integration tests in the `api4` package. Any changes to the plugin bundles require updating the corresponding signatures. First, import the public and private development key: ```sh gpg --import ./development-public-key.gpg gpg --import ./development-private-key.asc ``` This has to be done only once. Then update the signatures: ```sh gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign testplugin.tar.gz gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign --armor testplugin.tar.gz gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign testplugin-v0.0.2.tar.gz gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign --armor testplugin-v0.0.2.tar.gz gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign testplugin2.tar.gz gpg -u F3FACE45E0DE642C8BD6A8E64C7C6562C192CC1F --verbose --personal-digest-preferences SHA256 --detach-sign --armor testplugin2.tar.gz ``` Finally, include the updates bundles and signatures in your commit.
