Usage

Builders

Builders to help create both directories and files quickly for testing purposes.

// Create a directory quickly on disk
DirectoryInfo dir = DirectoryBuilder.InFileSystem
                        .WithPath(@"C:\Temp\Testing")
                        .EmptyIfExists()
                        .Build();


// Create a file quickly on disk
FileInfo file = FileBuilder.InFileSystem
                    .WithPath(@"C:\Temp\Testing\TestFile1.txt")
                    .WithSize(10)
                    .OverwriteIfExists(true)
                    .Build();

TestConnectionString & TestApiKey

The TestConnectionString and TestApiKey types both represent different types of single value string settings that live external to the test project.

These settings can be stored possibly in either an environment variable or file.

Example usage of TestConnectionString:

// Get reference to assembly that is running the tests
var assembly = Assembly.GetAssembly(typeof(SomeIntTests));

// Create an instance of the type. A number of default file paths will be set on FilePath
// when a reference to the containing assembly is passed on the constructor.
var testConn = new TestConnectionString(assembly);

// Set the name of a possible environment variable where the connection might be held
testConn.EnvironmentVarName = "MyIntTests-ConnString";

// Set extra file paths where the connection string might be held.
testConn.FilePaths.Add(@"X:\Secure\MyIntTests.connstring");

string connStr = testConn.GetValue();

TestSettings

The TestSettings type represents sets of test settings that live external to the test project in a JSON file.

Example custom settings type:

public class MyAppSettings
{
    public string MySecret1 { get; set; }

    public string MySecret2 { get; set; }
}

Example JSON settings file MyApp.settings.json (property name case is ignored):

{
  "MySecret1": "some secret 1",
  "MySecret2": "some secret 2"
}

Example code to retrie MyAppSettings:

// Get reference to assembly that is running the tests
var assembly = Assembly.GetAssembly(typeof(SomeIntTests));

// Create an instance of the type. A number of default file paths will be set on FilePath
// when a reference to the containing assembly is passed on the constructor.
var testSettings = new TestSettings(assembly);

// // Set extra file paths where the test settings might be held
testSettings.FilePaths.Add(@"X:\Secure\MyApp.settings.json");

MyAppSettings settings = testSettings.GetSettings<MyAppSettings>();

// settings.MySecret1 == "some secret 1"
// settings.MySecret2 == "some secret 2"

As well as defining and providing your own settings type you can also use the built in TestAzureSettings type.

For example:

TestAzureSettings settings = testSettings.GetAzureSettings();

// TestAzureSettings contains common Azure settings, including:
// SubscriptionId, TenantId, ClientId, ClientSecret etc.
