Classes

A metric to record information about CPU activity during a performance test.

XCTCPUMetric is a wrapper to XCTest.XCTCPUMetric.

A metric to record the time that elapses during a performance test.

XCTClockMetric is a wrapper to XCTest.XCTClockMetric.

A metric to record the physical memory that a performance test uses.

XCTMemoryMetric is a wrapper to XCTest.XCTMemoryMetric.

A metric to record the amount of data that a performance test logically writes to storage.

XCTStorageMetric is a wrapper to XCTest.XCTStorageMetric.

The primary class to define tests in XCTBeton.

Extends the capabilities of XCTestCase with measure(metrics:options:block:) and XCTAssertMetric(_:_:_:_:file:line:). You can use these features if you want to write performance tests with assertions.

The following example shows how you can write a simple assertion:

import XCTBeton

class PerformanceTests: XCTestCase {
  func test_measureSum() {
    measure {
      let _ = (1..<1000).reduce(0, +)
    }
    XCTAssertMetric(.clock, .timeMonotonic, .average(maximum: 0.001))
  }
}
