A modern runtime for JavaScript and TypeScript.
https://deno.com/
d592cf07d6
Previously:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: SourceRange,
pub steps: Vec<TestDefinition>,
}
pub struct TestDefinitions {
pub discovered: Vec<TestDefinition>,
pub injected: Vec<lsp_custom::TestData>,
pub script_version: String,
}
```
Now:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: Option<Range>,
pub is_dynamic: bool, // True for 'injected' module, not statically detected but added at runtime.
pub parent_id: Option<String>,
pub step_ids: HashSet<String>,
}
pub struct TestModule {
pub specifier: ModuleSpecifier,
pub script_version: String,
pub defs: HashMap<String, TestDefinition>,
}
```
Storing the test tree as a literal tree diminishes the value of IDs,
even though vscode stores them that way. This makes all data easily
accessible from `TestModule`. It unifies the interface between
'discovered' and 'injected' tests. This unblocks some enhancements wrt
syncing tests between the LSP and extension, such as this TODO:
