* Only pass in to the generation logic the cache key itself, so no other unaccounted inputs can be used. Unfortunately, this has not been done for any generators today.
* Be very, very careful.
* The cache has a builtin test, enabled with `UNSAFE_PILOT_ENABLE_RUNTIME_ASSERTIONS=true`, that runs in CI. This will panic if any key is written to with a different value.

In the dependency override we set a new value for the `admin_email` when creating the new `Settings` object, and then we return that new object.

Then we can test that it is used.

## Reading a `.env` file

          @Override
          public String pendingToString() {
            return "cause=[Because this test isn't done]";

    assertThat(testFuture.toString())
        .matches(
            "[^\\[]+\\[status=PENDING, info=\\[cause=\\[Because this test isn't done\\]\\]\\]");
    TimeoutException e = assertThrows(TimeoutException.class, () -> testFuture.get(1, NANOSECONDS));

## Тесты

Также в репозитории есть скрипт, который Вы можете запустить локально, чтобы протестировать весь код и сгенерировать отчеты о покрытии тестами в HTML:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>

		t.Run(fmt.Sprintf("Test_%d", i+1), func(t *testing.T) {
			cfg, err := ParseConfig(bytes.NewReader([]byte(tc.inputConfig)))
			if err != nil {
				t.Fatalf("Got unexpected error: %v", err)
