  Table driven tests , also known as parameterized tests, have became very popular over the past few years, due to their ability to eliminate repetition. Table driven tests make it quite a bit easier to re-use the same values for different sets of tests by just moving the table outside of the scope of the test function. Different tests may benefit from the same input, and each test may have completely different configration, concurrency etc... The table structure Well, think of it as a systematic way of testing your code by providing a set of inputs and expected outputs in a structured table format. Instead of writing individual test cases for each input-output pair, we organize them neatly in a table, making it easier to manage and maintain our tests. Each row in the table represents a separate test case, and the columns represent different aspects or parameters of the test, such as inputs, expected outputs, and any other relevant conditions. Here's a simplified example of what a...

  Introduction Testing software is like putting it through a series of challenges to make sure it's tough enough for real-world use. Whether we're testing each piece individually (unit testing) or how they all work together (integration testing), we need to be prepared for different situations. Sometimes, testing is tricky.There are times, when we need to isolate parts of our code from their dependencies. Also When we examine how different pieces of our application interact with each other.That's where tools like Mocks, Stubs, and Fakes come into the picture. In this Article, We'll explore What is Fake vs Stub vs Mock and their differences. So without delaying further, Let's dive deep into it! Fakes Vs Stubs Vs Mocks Fakes are a way for us to simulate objects and method functionality in our code without actually depending on a real object or method. Stubs are a type of fake that quietly fakes behavior and can return a predefined expected value, while a mock is a ty...

  Introduction: Condition Coverage is a popular testing technique that provides insights into the percentage of branches executed during testing. In this article, we'll explore what is Condition Coverage , Its importance, How it works, and many more! So Without delaying further, let's Start! What is Condition Coverage? Condition coverage in software testing is also known as Predicate Coverage. It guarantees that testing includes the execution of both branches in a decision, like an if statement. If a decision point has different conditions (using AND or OR), Condition coverage makes sure we've tested all the different combinations of conditions. Condition Coverage = (Number of tested conditions / Total number of conditions) * 100 This metric gives a percentage that indicates the proportion of branches executed during testing. Let's understand this with an example: function checkNumberSign(number) { let result; if (number > 0) { result = "Positi...
