XCTest can be built as part of the overall Swift package. When following [the instructions for building Swift](http://www.github.com/apple/swift), pass the `--xctest` option to the build script:

```
```sh
swift/utils/build-script --xctest
```

If you want to build just XCTest, use the `build_xctest.py` script at the root of the project. The `master` version of XCTest must be built with the `master` version of Swift.

If your install of swift is located at `/swift` and you wish to install XCTest into that same location, here is a sample invocation of the build script:

```
```sh
./build_script.py --swiftc="/swift/usr/bin/swiftc" --build-dir="/tmp/XCTest_build" --swift-build-dir="/swift/usr" --library-install-path="/swift/usr/lib/swift/linux" --module-install-path="/swift/usr/lib/swift/linux/x86_64"
```

### Additional Considerations for Swift on Linux

When running on the Objective-C runtime, XCTest is able to find all of your tests by simply asking the runtime for the subclasses of `XCTestCase`. It then finds the methods that start with the string `test`. This functionality is not currently present when running on the Swift runtime. Therefore, you must currently provide an additional property called `allTests` in your `XCTestCase` subclass. This method lists all of the tests in the test class. The rest of your test case subclass still contains your test methods.

```
```swift
class TestNSURL : XCTestCase {
var allTests : [(String, () -> ())] {
return [

Also, this version of XCTest does not use the external test runner binary. Instead, create your own executable which links `libXCTest.so`. In your `main.swift`, invoke the `XCTMain` function with an array of instances of the test cases that you wish to run. For example:

```
```swift
XCTMain([TestNSString(), TestNSArray(), TestNSDictionary()])
```
