In a similar vein, we can introduce parameters into our step definitions to help us avoid duplicated code. With string patterns, parameters can be specified using curly braces ({}), inside of which the type of the variable is indicated.
For example, our Then our API should respond with a <statusCode> HTTP status code step definition can be redefined as follows:
Then('our API should respond with a {int} HTTP status code', function (statusCode) { assert.equal(this.response.statusCode, statusCode);});
Here, we've replaced the hardcoded 400 HTTP status code with a placeholder, {int}, which indicates that the pattern should match an integer. Then, we are passing the value of the placeholder into the code ...
