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. --- Fixes #25718

|

///
|
|
/// ```ts
|
|
/// Deno.test("./base.ts$1-7.ts", async () => {

/// const logger = createLogger("my-awesome-module");

|

/// at the top level of the module.
|

///
|

/// To address this issue, the `export` keyword is removed so that the item can
|
|
/// stay in the `Deno.test` block's scope:
|
