Swift 测试传递参数

Question

有谁知道如何为快速测试提供命令行参数？

我试过:快速测试“myDBName”

但是我遇到了意外的参数错误。

可能的参数列表是:

OVERVIEW: Build and run tests

USAGE: swift test [options]

OPTIONS:
  --build-path            Specify build/cache directory [default: ./.build]
  --chdir, -C             Change working directory before any other operation
  --color                 Specify color mode (auto|always|never) [default: auto]
  --configuration, -c     Build with configuration (debug|release) [default: debug]
  --enable-prefetching    Enable prefetching in resolver
  --list-tests, -l        Lists test methods in specifier format
  --parallel              Run the tests in parallel.
  --skip-build            Skip building the test target
  --specifier, -s         Run a specific test class or method, Format: <test-module>.<test-case> or <test-module>.<test-case>/<test>
  --verbose, -v           Increase verbosity of informational output
  -Xcc                    Pass flag through to all C compiler invocations
  -Xlinker                Pass flag through to all linker invocations
  -Xswiftc                Pass flag through to all Swift compiler invocations
  --help                  Display available options

还有其他方法可以传递参数吗？ (环境变量等？)

Answer 1

您确实可以利用环境来做到这一点。

具有以下内容的测试:

final class HelloTests: XCTestCase {
    func testExample() {
        XCTAssertEqual(String(cString: getenv("SOMETHING")), "else")
    }

    static var allTests = [
        ("testExample", testExample),
    ]
}

会成功，使用swift命令行:

SOMETHING=else swift test
