method Deno.TestContext.step
TestContext.step(definition: TestStepDefinition): Promise<boolean>
Run a sub step of the parent test or step. Returns a promise
that resolves to a boolean signifying if the step completed successfully.
The returned promise never rejects unless the arguments are invalid.
If the test was ignored the promise returns `false`.
```ts
Deno.test({
name: "a parent test",
async fn(t) {
console.log("before the step");
await t.step({
name: "step 1",
fn(t) {
console.log("current step:", t.name);
}
});
console.log("after the step");
}
});
```
