Testing And Benchmarking in ActionScript

ActionScript does not have built-in unit testing or benchmarking capabilities like Go. However, we can create a similar structure using custom functions and a third-party testing framework like FlexUnit. Here’s an example of how we might implement testing in ActionScript:

package {
    import flexunit.framework.TestCase;
    import flexunit.framework.TestSuite;

    public class IntUtilsTest extends TestCase {
        public function IntUtilsTest(methodName:String = null) {
            super(methodName);
        }

        // This is our function to test
        public static function intMin(a:int, b:int):int {
            return a < b ? a : b;
        }

        // Basic test
        public function testIntMinBasic():void {
            var ans:int = intMin(2, -2);
            assertEquals("IntMin(2, -2) should return -2", -2, ans);
        }

        // Table-driven test
        public function testIntMinTableDriven():void {
            var tests:Array = [
                {a: 0, b: 1, want: 0},
                {a: 1, b: 0, want: 0},
                {a: 2, b: -2, want: -2},
                {a: 0, b: -1, want: -1},
                {a: -1, b: 0, want: -1}
            ];

            for each (var tt:Object in tests) {
                var ans:int = intMin(tt.a, tt.b);
                assertEquals("IntMin(" + tt.a + ", " + tt.b + ") should return " + tt.want, tt.want, ans);
            }
        }

        // Benchmarking in ActionScript is not as straightforward as in Go.
        // Here's a simple timing function that could be used for basic benchmarking:
        public function benchmarkIntMin():void {
            var startTime:Number = new Date().time;
            var iterations:int = 1000000;

            for (var i:int = 0; i < iterations; i++) {
                intMin(1, 2);
            }

            var endTime:Number = new Date().time;
            var duration:Number = (endTime - startTime) / 1000; // Convert to seconds
            trace("BenchmarkIntMin: " + iterations + " iterations in " + duration + " seconds");
        }

        // This method creates a TestSuite with all the test methods
        public static function suite():TestSuite {
            var suite:TestSuite = new TestSuite();
            suite.addTest(new IntUtilsTest("testIntMinBasic"));
            suite.addTest(new IntUtilsTest("testIntMinTableDriven"));
            return suite;
        }
    }
}

To run these tests, you would typically set up a test runner in your ActionScript project. The exact method depends on your development environment, but it might look something like this:

import flexunit.framework.TestSuite;
import flexunit.textui.TestRunner;

// In your main application file
var suite:TestSuite = IntUtilsTest.suite();
TestRunner.run(suite);

// Run the benchmark
var benchmark:IntUtilsTest = new IntUtilsTest();
benchmark.benchmarkIntMin();

This structure mimics the Go testing approach as closely as possible within the constraints of ActionScript. Note that:

We use FlexUnit, a popular testing framework for ActionScript, to structure our tests.
The TestCase class provides assertion methods like assertEquals.
We create a suite method to group our tests, similar to how Go groups tests in a file.
Benchmarking is implemented as a simple timing function, as ActionScript doesn’t have built-in benchmarking tools like Go.
The output and running process will be different from Go, depending on your ActionScript development environment.

Remember to adapt this structure to your specific ActionScript project setup and testing needs.
