I was assuming that TypeMock would automatically created recursive fakes and support nested calls to verify method calls. However, I had to use the below code
private static Environment SetUpFakeEnvironmentToGetSettings(int settingIndex, EnvironmentSettings settings)
{
var env = Isolate.Fake.Instance<Environment>();
Isolate.WhenCalled(() => env.Settings).WillReturn(settings);
Isolate.WhenCalled(() => settings.ElementAt(settingIndex)).WillReturn(Isolate.Fake.Instance<EnvironmentSetting>());
return env;
}
To get the below code working.
[TestMethod]
[Isolated]
public void UseTheFirstSettingInEnvironmentSettingsToSetAndGetTheDatabaseConnectionString()
{
const int firstSetting = 0;
var sets = Isolate.Fake.Instance<EnvironmentSettings>();
var env = SetUpFakeEnvironmentToGetSettings(firstSetting, sets);
var genv = new GenFormEnvironment(env);
try
{
var cs = genv.GenFormDatabaseConnectionString;
Isolate.Verify.WasCalledWithExactArguments(() => sets.ElementAt(firstSetting));
}
catch (Exception e)
{
Assert.Fail(e.ToString());
}
}
If I simply return Isolate.Fake.Instance<Environment>() without:
Isolate.WhenCalled(() => env.Settings).WillReturn(settings);
Isolate.WhenCalled(() => settings.ElementAt(settingIndex)).WillReturn(Isolate.Fake.Instance<EnvironmentSetting>());
then I get TypeMock errors. If I do not explicitly fake EnvironmentSettings, the I get a Verify exception telling me that ElementAt was not called.
Am I missing something?
