interface Deno.TestContext
Context that is passed to a testing function, which can be used to either
gain information about the current test, or register additional test
steps within the current test.
name: string
The current test name.
origin: string
The string URL of the current test.
optional
parent: TestContext
If the current test is a step of another test, the parent test context
will be set here.
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");
}
});
```
step(name: string,fn: (t: TestContext) => void | Promise<void>,): 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(
"a parent test",
async (t) => {
console.log("before the step");
await t.step(
"step 1",
(t) => {
console.log("current step:", t.name);
}
);
console.log("after the step");
}
);
```
step(fn: (t: TestContext) => void | Promise<void>): 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(async function aParentTest(t) {
console.log("before the step");
await t.step(function step1(t) {
console.log("current step:", t.name);
});
console.log("after the step");
});
```
