# Context
In the `playwright.config` file, we can custom the default `timeout`
property for `expect.toPass` by the property:
```ts title='playwright.config.ts'
export default defineConfig({
// ...
expect: {
toPass: {
timeout: 60_000,
},
},
});
```
However, we can't customize the `intervals` option. So the default value
is always `[100, 250, 500, 1000]`.
# Goal
Add the possibility to customize the intervals option from the
`playwright.config` file.
```ts title='playwright.config.ts'
export default defineConfig({
// ...
expect: {
toPass: {
timeout: 60_000,
intervals: [1000, 2000, 3000]
},
},
});
```
