Subject: [PATCH] Add support for running specific test files (#32)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds a new `.files()` method to the Builder API that allows running
specific test files instead of discovering all `.txt` files in a
directory. This mirrors the functionality of Go's testscript `Files`
parameter.
## New API
```rust
// Run only specific test files
testscript::run("testdata")
.files(["hello.txt", "exists.txt"])
.execute()
.unwrap();
// Combine with other features
testscript::run("testdata")
.files(["hello.txt", "exists.txt"])
.setup(|env| { /* setup code */ Ok(()) })
.condition("custom", true)
.preserve_work_on_failure(true)
.execute()
.unwrap();
```
## Benefits
- **Selective testing**: Run only specific test scenarios during
development
- **Faster CI**: Run subsets of tests in parallel jobs
- **Go compatibility**: Matches `testscript.Run(t,
testscript.Params{Files: []string{...}})`
- **Flexible paths**: Supports relative paths, absolute paths, and
filenames
## Implementation Details
- Adds optional `files` field to `RunParams`
- Enhances internal `run()` function to handle file lists vs glob
discovery
- Preserves execution order as specified by user
- Comprehensive error handling for missing files and invalid paths
- Full backward compatibility - existing code unchanged
## Path Support
```rust
testscript::run("testdata")
.files([
"hello.txt", // filename in testdata dir
"subdir/nested.txt", // relative path
"/abs/path/to/test.txt" // absolute path
])
.execute()
.unwrap();
```
The feature includes focused test coverage with 7 test cases covering
essential scenarios including error conditions and path types. Based on
feedback, redundant tests were removed to maintain a clean and
meaningful test suite.
Fixes imjasonh/testscript-rs#7

> ## Implementation
>
> - Extend the Builder API with a `.files()` method
> - Create a separate `run_files()` entry point
