Examples of MockEnvironmentProvider

The EnvironmentAbstractions.TestHelpers provides a helper implementation of IEnvironmentProvider which can be passed to classes to mock access to the environment.

By default, all existing values are set from the current environment.

[Fact]
public void MethodReturnsExpectedValue()
{
    IEnvironmentProvider environmentProvider = new MockEnvironmentProvider();
    
    MyClass instance = new MyClass(environmentProvider);

    string value = instance.Method();
}

To use an instance of the environment without any values already set, specify the useExistingEnvironmentValues parameter to the MockEnvironmentProvider constructor:

[Fact]
public void MethodReturnsExpectedValue()
{
    IEnvironmentProvider environmentProvider = new MockEnvironmentProvider(useExistingEnvironmentValues: false);

    // The only Environment property with a value will be UserName
    environmentProvider.UserName = "UserA";
}

To use an instance of the environment with existing environment variable values, specify the addExistingEnvironmentVariables parameter to the MockEnvironmentProvider constructor:

[Fact]
public void MethodReturnsExpectedValue()
{
    IEnvironmentProvider environmentProvider = new MockEnvironmentProvider(addExistingEnvironmentVariables: true);

    // All existing environment variables are set but UserName is overidden
    environmentProvider["UserName"] = "UserA";
}

Examples of MockEnvironmentVariableProvider

The EnvironmentAbstractions.TestHelpers provides a helper implementation of IEnvironmentVariableProvider which can be passed to classes to mock environment variable values.

Use a clean set of environment variables where only what is added is available

[Fact]
public void MethodReturnsExpectedValue()
{
    IEnvironmentVariableProvider environmentVariableProvider = new MockEnvironmentVariableProvider
    {
        ["Variable1"] = "Value1";
    };

    MyClass instance = new MyClass(environmentVariableProvider);

    string value = instance.Method();
}

To make all existing environment variables available, specify the addExistingEnvironmentVariables parameter to the MockEnvironmentVariableProvider constructor:

[Fact]
public void MethodReturnsExpectedValue()
{
    IEnvironmentVariableProvider environmentVariableProvider = new MockEnvironmentVariableProvider(addExistingEnvironmentVariables: true);

    environmentVariableProvider["UserName"] = @"User1";

    // Accessing environment variables returns actual values except %UserName% has been changed for just this test
}
