-# Test Sanitizers
-
-The test runner offers several sanitizers to ensure that the test behaves in a
-reasonable and expected way.
-
-### Resource sanitizer
-
-Certain actions in Deno create resources in the resource table
-([learn more here](./contributing/architecture.md)).
-
-These resources should be closed after you are done using them.
-
-For each test definition, the test runner checks that all resources created in
-this test have been closed. This is to prevent resource 'leaks'. This is enabled
-by default for all tests, but can be disabled by setting the `sanitizeResources`
-boolean to false in the test definition.
-
-```ts
-Deno.test({
-  name: "leaky resource test",
-  async fn() {
-    await Deno.open("hello.txt");
-  },
-  sanitizeResources: false,
-});
-```
-
-### Op sanitizer
-
-The same is true for async operation like interacting with the filesystem. The
-test runner checks that each operation you start in the test is completed before
-the end of the test. This is enabled by default for all tests, but can be
-disabled by setting the `sanitizeOps` boolean to false in the test definition.
-
-```ts
-Deno.test({
-  name: "leaky operation test",
-  fn() {
-    setTimeout(function () {}, 1000);
-  },
-  sanitizeOps: false,
-});
-```
-
-### Exit sanitizer
-
-There's also the exit sanitizer which ensures that tested code doesn't call
-`Deno.exit()` signaling a false test success.
-
-This is enabled by default for all tests, but can be disabled by setting the
-`sanitizeExit` boolean to false in the test definition.
-
-```ts
-Deno.test({
-  name: "false success",
-  fn() {
-    Deno.exit(0);
-  },
-  sanitizeExit: false,
-});
-
-// This test never runs, because the process exits during "false success" test
-Deno.test({
-  name: "failing test",
-  fn() {
-    throw new Error("this test fails");
-  },
-});
-```
