Trumpf.Coparoo.Waiting 1.2.0

Trumpf.Coparoo.Waiting

Trumpf.Coparoo.Waiting is a .NET library for C# that simplifies the process of waiting for conditions in automated tests. It provides a visual dialog to indicate the current state of the condition being evaluated, making it easier for testers to understand what is happening during test execution. The dialog will display in different colors to indicate whether the condition is true, false, or requires manual intervention.

Features

• Polls conditions and shows a visual waiting dialog.
• Red dialog indicates a false condition.
• Green dialog indicates a true condition.
• Grey dialog for manual intervention (e.g., safety-critical acknowledgements).
• Supports automatic and semi-automated testing.
• Improves test analysis and video clarity by showing real-time feedback.

Installation

You can install the package via NuGet:

dotnet add package Trumpf.Coparoo.Waiting

Usage

Waiting for a Condition

You can use the ConditionDialog.For() method to wait for a condition to become true. It displays a dialog showing the condition's state.

ConditionDialog.For(() => true, "Condition is true", TimeSpan.FromSeconds(2), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));

This will wait until the condition is true or the timeout is reached. The dialog will show the current state of the condition (red for false, green for true).

Handling Timeout and Exceptions

If the condition is false when the timeout is reached, a WaitForTimeoutException will be thrown with a descriptive message.

try
{
    ConditionDialog.For(() => false, "Condition is false", TimeSpan.FromSeconds(2), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));
}
catch (WaitForTimeoutException ex)
{
    Console.WriteLine(ex.Message); // Will print the timeout message
}

Example with Manual Intervention

For tests that require manual intervention (e.g., user approval), the dialog will show grey with instructions:

ConditionDialog.For(() => false, "Manual intervention required", TimeSpan.FromSeconds(10), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));

Repeating Conditions

You can repeat the condition check for a number of iterations, making it easy to track ongoing changes:

Enumerable.Range(0, 50).ToList().ForEach(_ => 
    ConditionDialog.For(() => true, "Repeated condition check", TimeSpan.FromSeconds(2), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100))
);

Test Cases

The library includes a series of tests to validate its functionality, including:

• Positive cases: Waiting until the condition is true without errors.
• Negative cases: Testing conditions where the timeout is exceeded or the condition is null/false.
• Manual interventions: Using the grey dialog to prompt the user for actions.
• Nested waits: Handling conditions with multiple nested waiting dialogs.

Example Test Cases

• Basic Test: Wait until a condition is true, then continue.

  [Test]
  public void IfTheConditionIsTrue_ThenNoExceptionIsThrown()
  {
      ConditionDialog.For(() => true, "Condition is true", TimeSpan.FromSeconds(2), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));
  }
  

• Timeout Test: Timeout occurs if the condition remains false.

  [Test]
  public void IfTheConditionIsFalse_ExceptionIsThrown_WithExceptionMessage()
  {
      Assert.Throws<WaitForTimeoutException>(() =>
      {
          ConditionDialog.For(() => false, "Condition is false", TimeSpan.FromSeconds(2), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));
      });
  }
  

• Manual Intervention Test: Show a grey dialog for user intervention.

  [Test]
  public void IfTheConditionRequiresManualIntervention_ThenGreyDialogIsShown()
  {
      ConditionDialog.For(() => false, "Manual intervention required", TimeSpan.FromSeconds(10), TimeSpan.FromSeconds(1), TimeSpan.FromMilliseconds(100));
  }
