This post shows how to capture arguments our codes passed to a mock’s method. To do this, a method must accept reference types. Then, we use Mockito.verify() method. Then, pass an instance of ArgumentCaptor to the mock’s method. Capture Argument
Using JDK 9 with Eclipse Luna
JDK 9 works with Eclipse Mars [wp_ad_camp_5] First and foremost, Eclipse Luna does not work with JDK 9 because of JEP 220: Modular Run-Time Images. There is Eclipse Mars for that. Updating eclipse.ini to use JDK 9 JEP 220 changed
Find out if an object is a mock or spy in Mockito
The need for it [wp_ad_camp_5] Finding out if an object is a mock or spy in Mockito may not (or never) be part of your usual automated unit tests but in some cases (advanced usage of JUnit/Mockito) you may need
Mockito Spy
Spy Objects [wp_ad_camp_5] A Mockito spy allows us to create a spy object from a real object with similar behavior where each method can be stubbed out when needed. It is ideal for testing legacy code as you cannot invoke
Execute Tests in Order in JUnit 4
Using @FixMethodOrder [wp_ad_camp_5] To execute tests in a order in JUnit 4, annotate the class with @FixedMethodOrder passing one of enum MethodSorters items as parameter. Either one of the following can be used are parameter to @FixMethodOrder. MethodSorters.NAME_ASCENDING: This sorts
JavaScript Object Creation and Object Methods and Properties
[wp_ad_camp_1] If you’ve read this, it merely declares JavaScript can do OOP. It did not talked about other (more advanced) OOP stuff like access modifiers, encapsulation – behaviors and properties, and inheritance. On this article, we’ll talk more on object
Check if a value is in an Array in JavaScript
Given an array of strings, we want to know if a particular string value is in that array. Here we’ll use the Array object’s .indexOf function.
JavaScript scope in functions vs Java scope in methods
For years, JavaScript to me was a mere validation tool or script for web applications. I hated it. I avoided using it. This time JavaScript gets the same respect from me as Java does. If you plan to “own” (or master if you can) JavaScript and you are coming from blocked-scoped languages like Java, C#, C and C++, this is one of key things you need to keep in mind…
Working with Reference Types in JavaScript
JavaScript has both primitive and reference types. It has three primitive types: string, numeric, and boolean. Internally, these are small and fixed-sized collection of bytes that are easily and predictably manipulated at the low (primitive) levels of the JavaScript interpreter. Example of strings are ‘This is a string’ and “This is another string”. Numeric values – 1, and 3.1416. Boolean values – true or false. On the other hand, reference types are different. They include objects (including JS built-in objects), Arrays, and functions. Essentially, they can have any number of properties or elements with various types (both primitives and references), so they cannot be manipulated as easily as fixed-size primitive v
JavaScript Arrays with Elements of Different Data Types
Array with different types of data? Weird stuff! Generally, an array is collection of similar items. In Computer Science 101, this means the items are of the same data type. We have an array of integers, boolean values or strings. But in JavaScript, arrays can have elements of different types.
