  • Practical Methods for Programmer Testing
    JUnit Recipes Practical Methods for Programmer Testing J.B.Rainsberger with contributions by Scott Stirling MANNING JUnit Recipes Practical Programmer Testing Methods by J.B. Rainsberger Chapter 1 Copyright 2004 Manning Publications Rainsberger.book Page 3 Monday, June 28, 2004 6:42 PM Fundamentals This chapter covers ■ An introduction to Programmer Testing ■ Getting started with JUnit ■ A few good practices for JUnit ■ Why testing replaces debugging 3 Rainsberger.book Page 4 Monday, June 28, 2004 6:42 PM 4 CHAPTER 1 Fundamentals We hate debugging. You look up at the clock to see how late it is because you still have a handful of defects that need to be fixed tonight. Welcome to the “fix” phase of “code and fix,” which is now entering its third month. In that time, you have begun to forget what your home looks like. The four walls of your office—assuming you even have four walls to look at—are more familiar than you ever wanted them to be. You look at the “hot defects” list and see one problem that keeps coming back. You thought you fixed that last week! These testers...when will they leave you alone?! Fire up the debugger, start the application server—grab a coffee because you have five minutes to kill—set a breakpoint or two, enter data in 10 text fields and then press the Go button. As the debugger halts at your first breakpoint, your goal is to figure out which object insists on sending you bad data. As you step through the code, an involuntary muscle spasm—no doubt from lack of sleep—causes you to accidentally step over the line of code that you think causes the problem.

  • Bringing Test-Driven Development to Web Service Choreographies
    Journal of Systems and Software • October 2014 • http://www.sciencedirect.com/science/article/pii/S016412121400209X Bringing Test-Driven Development to Web Service Choreographies Felipe Besson,Paulo Moura,Fabio Kon Dejan Milojicic Department of Computer Science Hewlett Packard Laboratories University of São Paulo Palo Alto, USA {besson, pbmoura, kon}@ime.usp.br [email protected] Abstract Choreographies are a distributed approach for composing web services. Compared to orchestrations, which use a centralized scheme for distributed service management, the interaction among the chore- ographed services is collaborative with decentralized coordination. Despite the advantages, choreography development, including the testing activities, has not yet evolved sufficiently to support the complexity of the large distributed systems. This substantially impacts the robustness of the products and overall adoption of choreographies. The goal of the research described in this paper is to support the Test-Driven Development (TDD) of choreographies to facilitate the construction of reliable, decentralized distributed systems. To achieve that, we present Rehearsal, a framework supporting the automated testing of chore- ographies at development-time. In addition, we present a choreography development methodology that guides the developer on applying TDD using Rehearsal. To assess the framework and the methodology, we conducted an exploratory study with developers, whose result was that Rehearsal was considered very helpful for the application of TDD and that the methodology helped the development of robust choreographies. Keywords: Automated testing, Test-Driven Development, Web service choreographies I. Introduction Service-Oriented Architecture (SOA) is a set of principles and methods that uses services as the building blocks for the development of distributed applications.

  • Testen Mit Mockito.Pdf
    Testen mit Mockito http://www.vogella.com/tutorials/Mockito/article.html Warum testen? Würde dies funktionieren, ohne es vorab zu testen? Definition von Tests • Ein Softwaretest prüft und bewertet Software auf Erfüllung der für ihren Einsatz definierten Anforderungen und misst ihre Qualität. Die gewonnenen Erkenntnisse werden zur Erkennung und Behebung von Softwarefehlern genutzt. Tests während der Softwareentwicklung dienen dazu, die Software möglichst fehlerfrei in Betrieb zu nehmen. Arten von Tests • Unit-Test: Test der einzelnen Methoden einer Klasse • Integrationstest: Tests mehrere Klassen / Module • Systemtest: Test des Gesamtsystems (meist GUI-Test) • Akzeptanztest / Abnahmetest: Test durch den Kunden, ob Produkt verwendbar • Regressionstest: Nachweis, dass eine Änderung des zu testenden Systems früher durchgeführte Tests erneut besteht • Feldtest: Test während des Einsatzes • Lasttest • Stresstest • Smoke-Tests: (Zufallstest) nicht systematisch; nur Funktion wird getestet Definitionen • SUT … system under test • CUT … class under test TDD - Test Driven Development Test-Driven Development with Mockito, packt 2013 JUnit.org Hamcrest • Hamcrest is a library of matchers, which can be combined in to create flexible expressions of intent in tests. They've also been used for other purposes • http://hamcrest.org/ • https://github.com/hamcrest/JavaHamcrest • http://www.leveluplunch.com/java/examples/hamcrest- collection-matchers-junit-testing/ • http://grepcode.com/file/repo1.maven.org/maven2/ org.hamcrest/hamcrest-library/1.3/org/hamcrest/Matchers.java Test Doubles Warum Test-Doubles? • A unit test should test a class in isolation. Side effects from other classes or the system should be eliminated if possible. The achievement of this desired goal is typical complicated by the fact that Java classes usually depend on other classes.

  • Mock Objects for Testing Java Systems Why and How Developers Use Them, and How They Evolve
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2019 Mock objects for testing java systems Why and how developers use them, and how they evolve Spadini, Davide ; Aniche, Maurício ; Bruntink, Magiel ; Bacchelli, Alberto Abstract: When testing software artifacts that have several dependencies, one has the possibility of either instantiating these dependencies or using mock objects to simulate the dependencies’ expected behavior. Even though recent quantitative studies showed that mock objects are widely used both in open source and proprietary projects, scientific knowledge is still lacking on how and why practitioners use mocks. An empirical understanding of the situations where developers have (and have not) been applying mocks, as well as the impact of such decisions in terms of coupling and software evolution can be used to help practitioners adapt and improve their future usage. To this aim, we study the usage of mock objects in three OSS projects and one industrial system. More specifically, we manually analyze more than 2,000 mock usages. We then discuss our findings with developers from these systems, and identify practices, rationales, and challenges. These results are supported by a structured survey with more than 100 professionals. Finally, we manually analyze how the usage of mock objects in test code evolve over time as well as the impact of their usage on the coupling between test and production code. Our study reveals that the usage of mocks is highly dependent on the responsibility and the architectural concern of the class. Developers report to frequently mock dependencies that make testing difficult (e.g., infrastructure-related dependencies) and to not mock classes that encapsulate domain concepts/rules of the system.

  • Java Testing with Spock by Konstantinos Kapelonis
    SAMPLE CHAPTER Konstantinos Kapelonis FOREWORD BY Luke Daley MANNING Java Testing with Spock by Konstantinos Kapelonis Sample Chapter 1 Copyright 2016 Manning Publications brief contents PART 1FOUNDATIONS AND BRIEF TOUR OF SPOCK ................... 1 1 ■ Introducing the Spock testing framework 3 2 ■ Groovy knowledge for Spock testing 31 3 ■ A tour of Spock functionality 62 PART 2STRUCTURING SPOCK TESTS ...................................... 89 4 ■ Writing unit tests with Spock 91 5 ■ Parameterized tests 127 6 ■ Mocking and stubbing 157 PART 3SPOCK IN THE ENTERPRISE ...................................... 191 7 ■ Integration and functional testing with Spock 193 8 ■ Spock features for enterprise testing 224 Part 1 Foundations and brief tour of Spock Spock is a test framework that uses the Groovy programming language. The first part of the book expands on this by making sure that we (you, the reader, and me, the author) are on the same page. To make sure that we are on the same page in the most gradual way, I first define a testing framework (and why it’s needed) and introduce a subset of the Groovy syntax needed for writing Spock unit tests. I know that you’re eager to see Spock tests (and write your own), but some features of Spock will impress you only if you’ve first learned a bit about the goals of a test framework and the shortcomings of current test frameworks (for example, JUnit). Don’t think, however, that this part of the book is theory only. Even at this early stage, this brief tour of Spock highlights includes full code listings and some out-of-the-ordinary examples.

Different applications come with different testing needs, and it’s hard to predict what parts of Spock will be more useful to you beforehand. This chapter covers a bit of all major Spock capabilities to give you a bird's-eye view of how Spock works. I won’t focus on all the details yet because these are explained in the coming chapters. The purpose of this chapter is to act as a central hub for the whole book. You can read this chapter and then, according to your needs, decide which of the com- ing chapters is of special interest to you.
