+ ## Testing
58
+
59
+ The repo includes three types of tests: e2e tests in the repo that use Playwright, integration and
60
+ unit tests that use Vitest.
61
+
62
+ By default the e2e, integration and unit tests run against the latest version of Next.js. To run
63
+ tests against a specific version, set the ` NEXT_VERSION ` environment variable to the desired
64
+ version.
65
+
66
+ By default, PRs will run the tests against the latest version of Next.js. To run tests against
67
+ ` latest ` , ` canary ` and ` 13.5.1 ` , apply the ` test all versions ` label to the PR when you create it.
68
+ These also run nightly and on release PRs.
69
+
70
+ ### Integration testing
71
+
72
+ > ** Prerequisite** Run ` npm run build ` before running integration tests.
73
+
74
+ How to add new integration test scenarios to the application:
75
+
76
+ 1 . Create a new folder under ` tests/fixtures/<your-name> `
77
+ 2 . Adapt the ` next.config.js ` to be a standalone application
78
+ 3 . Create a ` postinstall ` script that runs the ` next build ` . It's important to notice that the
79
+ integration tests rely on a already built next.js application in this folder. They rely on the
80
+ ` .next ` folder.
81
+ 4 . Add your test
82
+
83
+ > Currently the tests require a built version of the ` dist/run/handlers/cache.cjs ` so you need to
84
+ > run ` npm run build ` before executing the integration tests.
85
+
86
+ In addition, the integration tests need to be prepared before first use. You can do this by running
87
+ ` npm run pretest ` . To speed up this process and build only the fixtures whose name starts with a
88
+ given prefix, run ` npm run pretest -- <prefix> ` .
89
+
90
+ ### E2E testing
91
+
92
+ > ** Prerequisite**
93
+ >
94
+ > Needs the ` netlify-cli ` installed and being logged in having access to Netlify Testing
95
+ > Organization or providing your own site ID with NETLIFY_SITE_ID environment variable.
96
+
97
+ The e2e tests can be invoked with ` npm run e2e ` and perform a full e2e test. This means they do the
98
+ following:
99
+
100
+ 1 . Building the next-runtime (just running ` npm run build ` in the repository)
101
+ 2 . Creating a temp directory and copying the provided fixture over to the directory.
102
+ 3 . Packing the runtime with ` npm pack ` to the temp directory.
103
+ 4 . Installing the runtime from the created zip artifact of ` npm pack ` (this is like installing a
104
+ node_module from the registry)
105
+ 5 . Creating a ` netlify.toml ` inside the temp directory of the fixture and adding the runtime as a
106
+ plugin.
107
+ 6 . Running ` netlify deploy --build ` invoking the runtime. This will use the
108
+ [ next-runtime-testing] ( https://app.netlify.com/sites/next-runtime-testing/overview ) as site to
109
+ deploy to.
110
+ 7 . Using the ` deployId ` and ` url ` of the deployed site to run some
111
+ [ playwright] ( https://playwright.dev/ ) tests against, asserting the correctness of the runtime.
112
+ 8 . After the tests where run successfully, it will delete the deployment again and clean everything
113
+ up. In case of a failure, the deploy won't be cleaned up to leave it for troubleshooting
114
+ purposes.
115
+
116
+ > [ !TIP] If you'd like to always keep the deployment and the local fixture around for
117
+ > troubleshooting, run ` E2E_PERSIST=1 npm run e2e ` .
118
+
119
+ ### Next.js tests
120
+
121
+ There is a script ` run-local-test.sh ` and GitHub workflow that runs the e2e tests from the Next.js
122
+ repo against this repo. It requires that ` next.js ` is checked out in the same parent directory as
123
+ this repo, and is run from this repo with ` ./run-local-test.sh your-test-pattern-here ` .
124
+
125
+ #### cleanup old deploys
126
+
127
+ To cleanup old and dangling deploys from failed builds you can run the following script:
128
+
129
+ ``` bash
130
+ npx tsx ./tools/e2e/cleanup-deploys.ts
131
+ ```
132
+
133
+ This will cleanup all created deploys on the
134
+ [ next-runtime-testing] ( https://app.netlify.com/sites/next-runtime-testing/overview ) site.
