This commit fixes issues with the pseudo test file generation logic,
namely:
- `export`s declared in snippets
- auto import insertion for `default export`
## Case 1: `export`s declared in snippets
In the previous implementation, `export`s declared in snippets were
moved to the top level of the module in the generated pseudo test file.
This is required because `export` must be at the top level.
This becomes a problem if such a `export` has a body, containing a
reference to a local variable. Suppose we extract this snippet from
JSDoc:
```ts
const logger = createLogger("my-awesome-module");
export function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
```
This gets converted into the following invalid code (note that `export
function sum` is moved to the top level, but its body references
`logger` variable which can't be referenced from here):
```ts
export function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
Deno.test("./base.ts$1-7.ts", async () => {
const logger = createLogger("my-awesome-module");
});
```
To resolve this issue, this commit adds a logic to remove the `export`
keyword, allowing the exported items to stay in the `Deno.test` block
scope, like so:
```ts
Deno.test("./base.ts$1-7.ts", async () => {
const logger = createLogger("my-awesome-module");
function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
});
```
## Case 2: default export
Previously `default export foo` was not captured by the export
collector, so auto import insertion didn't work for this case. To put it
concretely, the following code snippet didn't work when run with `deno
test --doc` because `import foo from "file:///path/to/mod.ts"` didn't
get inserted automatically:
```ts
/**
* ```ts
* console.log(foo);
* ```
*
* @module
*/
const foo = 42;
export default foo;
```
This commit fixes this issue and the above example works fine.
