# Sample CLI Tool Example
|
||||
|
||||
This directory demonstrates how to use `testscript-rs` to test a CLI application.
|
||||
|
||||
## What's Here
|
||||
|
||||
- **`src/main.rs`** - A sample CLI tool with various subcommands
|
||||
- **`tests/integration_test.rs`** - Integration test using testscript-rs
|
||||
- **`testdata/`** - Test scripts in `.txtar` format
|
||||
|
||||
## The CLI Tool
|
||||
|
||||
The sample CLI tool supports:
|
||||
- `count` - Count lines, words, or characters in files
|
||||
- `grep` - Search for patterns in files
|
||||
- `create` - Create files with optional content
|
||||
- `remove` - Remove files
|
||||
- `list` - List directory contents
|
||||
|
||||
## The Tests
|
||||
|
||||
The integration test demonstrates key testscript-rs features:
|
||||
|
||||
1. **Setup Hook** - Compiles the CLI binary before running tests
|
||||
2. **Binary Testing** - Tests the actual compiled binary
|
||||
3. **File Operations** - Creates files, checks existence, compares content
|
||||
4. **Output Validation** - Checks stdout/stderr with regex patterns
|
||||
5. **Error Testing** - Verifies error conditions with negated commands
|
||||
|
||||
## Running the Tests
|
||||
|
||||
```bash
|
||||
cargo test
|
||||
```
|
||||
|
||||
This will:
|
||||
1. Compile the `sample-cli` binary
|
||||
2. Copy it to each test's temporary directory
|
||||
3. Run all `.txt` test scripts in `testdata/`
|
||||
4. Report results
|
||||
|
||||
## Example Test Script
|
||||
|
||||
```
|
||||
# Test basic functionality
|
||||
exec ./sample-cli --version
|
||||
stdout "sample-cli 1.0"
|
||||
|
||||
# Test file operations
|
||||
exec ./sample-cli create hello.txt --content "Hello, World!"
|
||||
exists hello.txt
|
||||
exec ./sample-cli count hello.txt
|
||||
stdout "hello.txt: 1"
|
||||
|
||||
# Test cleanup
|
||||
exec ./sample-cli remove hello.txt
|
||||
! exists hello.txt
|
||||
```
|
||||
|
||||
This demonstrates how testscript-rs makes CLI testing both powerful and readable!
