Description
Deequ is an innovative library that extends Apache Spark to create "unit tests for data," aiming to assess the quality of extensive datasets. We welcome any feedback and contributions from users. The library requires Java 8 for operation. It is important to note that Deequ version 2.x is compatible exclusively with Spark 3.1, and the two are interdependent. For those using earlier versions of Spark, the Deequ 1.x version should be utilized, which is maintained in the legacy-spark-3.0 branch. Additionally, we offer legacy releases that work with Apache Spark versions ranging from 2.2.x to 3.0.x. The Spark releases 2.2.x and 2.3.x are built on Scala 2.11, while the 2.4.x, 3.0.x, and 3.1.x releases require Scala 2.12. The primary goal of Deequ is to perform "unit-testing" on data to identify potential issues early on, ensuring that errors are caught before the data reaches consuming systems or machine learning models. In the sections that follow, we will provide a simple example to demonstrate the fundamental functionalities of our library, highlighting its ease of use and effectiveness in maintaining data integrity.
Description
Mocking serves as an effective method to enhance the readability and maintainability of code during testing. In a series of three articles, I aim to explore the foundational concepts, features, and unique aspects of the MockK library. This innovative open-source library, available on GitHub, is dedicated to simplifying the mocking process in Kotlin. When it comes to property injection, the library first attempts to align properties by their names, followed by matching them based on class or superclass hierarchies. For further customization, users can refer to the lookupType parameter. Notably, property injection continues to function even when private visibility is enforced. Additionally, when selecting constructors for injection, the library prioritizes those with the highest number of arguments, proceeding to those with fewer. This thoughtful design enhances the user experience and flexibility in testing scenarios.
