Hamcrest vs. Assert. J DZone Java. During RESTful API testing, its not uncommon that you would need to call a REST endpoint and validate its response to check its functionality. But how you can validate if something is working correctly or not The answer is assertions. Assertions are the cornerstone of the complete testing process, whether RESTful APIs or other components. When we say testing assertions, we mean checking that a boolean expression is true, unless there is an issue or bug with the tested use case. Download Instruction Manual For Monster Jam Pc here. In RESTful API testing, you might deal with API specific assertions like response codes or length validation. In addition, there will always be plenty of situations where you would need to perform general assertions on a daily basis even if you are only working with APIs. These could be variable validation, dates comparison, and so on. In this article, we are going to talk about two of the most popular Java assertion frameworks available with free access, which can be used in any of your projects. They can be used as part of your RESTful API testing, but also in any another check which you need to perform in your tests. Recent Articles.

A week or so ago I posted a piece called CodeKata, suggesting that as developers we need to spend more time just practicing writing throwaway code just to get the. Lets compare two popular open Java assertion frameworks, Hamcrest and AssertJ, for testing RESTful APIs. Check out their features, syntax, and other perks. The names of these frameworks are Assert. J and Hamcrest, and we will compare their open source engagement, syntax, class structure and functionality. Hamcrest is one of the most well known Java frameworks, which helps writing tests in the Java programming language. An interesting fact about the name of the framework It was created as an anagram to the word matchers, which are logically equal to assertions. Due to the high popularity of the framework, it was later ported to other programming languages like C, C, Objective C, Python, Action. Script 3, PHP, Java. Top 30 Programming interview questions Programming questions are an integral part of any Java or C programmer or software analyst interview. No matter on which. Script, Erlang, and R. Assert. J is not as well known as Hamcrest, but at the same time, its popularity has been growing pretty fast over the last few years. As opposed to Hamcrests classic assertion syntax, which was inherited from the default Java testing framework JUnit, the main idea of Assert. J is that it provides fluent syntax. The main goal of that is to improve code readability. Its worth mentioning that Assert. J is a fork of the FEST Assert project, which was the first step of Assert. J creation. Now lets get started with our comparison. Open Source Community Engagement and General Popularity. Its always a good sign when you choose a framework that has an active community around it. The main sign of an active community is activity in the framework repository, which basically means ongoing development and maintenance. If a framework is open source, you can always find its code repository and verify how often it has new code. Java. Hamcrestjoel costigliolaassertj. As you can see, Assert. J has had a more stable development pattern during the last years, and there are still commits on a monthly basis. Now lets take a look at the frameworks general popularity. Lets check out what Google Trends shows us over the past year. The only way to control the size of stack within process is start a new Thread. But you can also control by creating a selfcalling sub java process with Xss parameter. As you can see, Hamcrest definitely has a wider audience. But on the other hand, it seems that there is growth albeit small in Assert. Js popularity pattern over the last 1. Hamcrest, on the other hand, stays on the same level. You might wonder why Hamcrest has gained wider popularity at this point. This is probably because Hamcrest has a much longer life cycle. The first version of Hamcrest was presented in the Maven repository as early as May 2. Assert. J was added to the Maven repository only in March 2. Game Of Thrones Novel Pdf Indonesia'>Game Of Thrones Novel Pdf Indonesia. So it might be fair to compare trends over the past 5 years Now you can see the reason for the difference. When the first version of Assert. J was developed, Hamcrest already had a large crowd and was the main assertion library, in addition to default tools provided by commonly used test frameworks. But why then would someone want to create one more framework when there is already a list of available options to achieve the same goals Thats exactly what we are going to investigate. Syntax. While both tools do their jobs quite well, the syntax difference is quite noticeable. Lets go over the main syntax of both frameworks, based on some basic assertion examples Simple Assertionsassert. Thata, equal. Tob Hamcrest. Thata. is. Equal. Tob Assert. JDates Assertionsassert. Thattomorrow, is. Aftertoday Hamcrest. Thattomorrow. is. Aftertoday Assert. JList Assertionsassert.

Value Hamcrest. Thatactual. is. Null Assert. JAssertions With a Custom Messageassert. ThatError, a, equal. Tob Hamcrest. Thata. Equal. Tob. overriding. Error. MessageError Assert. JIts up to you which syntax you like most, but for me, Assert. J feels more natural and easy to read. Assertion Class Structure. In addition to the syntax difference, these frameworks have a different class hierarchy. While Assert. J provides only one static class that contains all available assertions, Hamcrest has different classes. If your file contains many assertions of different types, all your classes will be full of such imports import static org. Core. Matchers. equal. To. import static org. Matchers. empty. import static org. Swat 4 Weapons. Core. Matchers. not. Matchers. has. Size. Core. Matchers. null. Value. import static org. Matcher. Assert. assert. That It doesnt take too much effort from you to maintain all these imports, as all main development environments handle imports automatically. But it is still nice and simple when your code is cleaner, like in the case of Assert. J import static org. Assertions. Due to the same reason, Assert. J provides more convenient autosuggestions, because you dont need to memorize and guess which class matches you need to use to find the required assertion Soft Assertion Functionality. While both frameworks provide wonderful functionality to perform classic assertions, only Assert. J provides you with something extra. This something is the concept of soft assertions. Soft assertions allow you to perform multiple checks and see results for all of them. For unit tests, there is a good pattern to keep one assertion for each unit test. But do not forget that the same assertion library can be used in different integration tests where multiple assertions are the common practice. Assert. J soft assertions can be used this way Test. User user new UserYuri, Bushnev, bushnevyurigmail. Soft. Assertions softly new Soft. Assertions. softly. Thatuser. is. Not. Null. softly. assert. Thatuser. get. Name. Equal. ToYuri. Thatuser. Surename. Equal. To. Thatuser. get. Email. Equal. Tobushnevyurigmail. All. As you can see, its not too complicated. In the example above, we are expecting two assertion errors during the validation of the surname and the email. A standard way would require having three assertions one by one. Then, we would only see the first failed assertion about the surname while the issue in the email would be hidden until the surname would be fixed. Such issues are often reproducible in real life when regression testing complicated applications when some bugs are caught quickly during the first test run, but many other bugs can be missed and found only later, because tests can not go further until the failed step has been fixed.
