测试您的活动

实施新活动后，测试其是否按预期工作非常重要。您可以通过以下方式之一测试您的活动。

单元测试

测试活动代码的最简单、最快的方法是编写隔离活动代码并测试各个方案的单元测试。

例如：

[Theory]
[InlineData(1, Operation.Add, 1, 2)]
[InlineData(3, Operation.Subtract, 2, 1)]
[InlineData(3, Operation.Multiply, 2, 6)]
[InlineData(6, Operation.Divide, 2, 3)]
public void Calculator_ReturnsAsExpected(int firstNumber, Operation operation, int secondNumber, int expectedResult)
{
    var calculator = new Calculator()
    {
        SelectedOperation = operation
    };

    var result = calculator.ExecuteInternal(firstNumber, secondNumber);

    Assert.Equal(expectedResult, result);
}[Theory]
[InlineData(1, Operation.Add, 1, 2)]
[InlineData(3, Operation.Subtract, 2, 1)]
[InlineData(3, Operation.Multiply, 2, 6)]
[InlineData(6, Operation.Divide, 2, 3)]
public void Calculator_ReturnsAsExpected(int firstNumber, Operation operation, int secondNumber, int expectedResult)
{
    var calculator = new Calculator()
    {
        SelectedOperation = operation
    };

    var result = calculator.ExecuteInternal(firstNumber, secondNumber);

    Assert.Equal(expectedResult, result);
}

在此示例中，我们将简单地创建Calculator类的新实例并调用ExecuteInternal函数。没有与此上下文中的活动具体相关的内容，基本的单元测试原则适用。

要查看示例，请前往 GitHub 中的示例“计算器”活动。

工作流测试

工作流测试是一种单元测试，它依赖于WorkflowInvoker类将活动放置在工作流中，并像 UiPath 机器人运行一样运行该活动。

让我们看一下这个示例：

[Fact]
public void Divide_ReturnsAsExpected()
{
    var activity = new Calculator()
    {
        FirstNumber = 4,
        SecondNumber = 2,
        SelectedOperation = Operation.Divide
    };

    var runner = new WorkflowInvoker(activity);
    runner.Extensions.Add(() => workflowRuntimeMock.Object);

    var result = runner.Invoke(TimeSpan.FromSeconds(1)); //the runner will return a dictionary with the values of the OutArguments

    //verify that the result is as expected
    Assert.Equal(2, result["Result"]);

    //verify that we logged a message
    workflowRuntimeMock.Verify(x => x.LogMessage(It.IsAny<LogMessage>()), Times.Once);
}[Fact]
public void Divide_ReturnsAsExpected()
{
    var activity = new Calculator()
    {
        FirstNumber = 4,
        SecondNumber = 2,
        SelectedOperation = Operation.Divide
    };

    var runner = new WorkflowInvoker(activity);
    runner.Extensions.Add(() => workflowRuntimeMock.Object);

    var result = runner.Invoke(TimeSpan.FromSeconds(1)); //the runner will return a dictionary with the values of the OutArguments

    //verify that the result is as expected
    Assert.Equal(2, result["Result"]);

    //verify that we logged a message
    workflowRuntimeMock.Verify(x => x.LogMessage(It.IsAny<LogMessage>()), Times.Once);
}
