function runTests(tests, hash) {
        _.each(tests, (expectedString, templateString) => {
            it(`${templateString} resolves to '${expectedString}'`, function () {
                shouldCompileToExpected(templateString, hash, expectedString);
            });
        });
    }
Run tests takes a list of tests & a data hash in the form of two objects
The key is the template string, the value is the expected value when the template is compiled with the given hash object

@param {object} tests
@param {object} hash
