Cucumber.js and BDD aren't new kids on the block. Cucumber.js is a powerful testing framework. When written in pure code, this can become quite a verbose sentence.

One is to use the Cucumber DataTable class, which provides a number of helper methods to extract values from the table, or to convert the rows into a more usable form. Cucumber supports the pretty format, which enables Cucumber to generate test reports in HTML format. As an example, you could name a TDD-style test “getPremiumCustomerDiscountTest”, whereas in BDD you would name it something like “givenAPremiumCustomer_WhenWeGetTheDiscount_ItShouldReturnTenPercent.”. An inefficient way of doing this is to write step for each data entry. These cookies will be stored in your browser only with your consent.
