Answer 1

From ConfigurationFactory.java , this exception is thrown only if the method readTree from ObjectMapper returns null.

• Look at ConfigurationSourceProvider derived class that you are passing to build method, as it is not handling IOException properly ( I can assume you are using a mocked one);
• Look at path argument, it seems you should be passing "dropwizard-angular- example-master\\target\\test-classes\\integration.yml" instead of "dropwizard-angular-example-master\\target\\test-classes\\integration.yml" *first path has an empty space just after dropwizard-angular-

If your dropwizard-config file (ie integration.yml ) is in test/resources directory, you don't need to use ResourceHelpers.resourceFilePath("integration.yml") to pass full config path into DropwizardAppExtension as a param, you should only pass its name (eg "integration.yml")

private static DropwizardAppExtension<MyDropwizardConfiguration> RULE = new DropwizardAppExtension<>(
            MyDropwizardApplication.class, "integration.yml");
