Dependency Injection and Mock on Software and TestingVeng, Mengkeang January 2014 (has links)
Software testing has been integrated within software development life cycle due to its importance in assuring software quality, software safety, and customers' satisfaction. However, problems in software testing are prominent among software developers as system grows in size and complexity. Dependency injection becomes an appealing solution for developers with its practicality to improve software design, improve testability, and enable mock testing technique. The study aims to discover the extent to which the dependency injection facilitates software design and software testing. In addition, the effect of mock practice on testing is also assessed. Metrics for investigation are defined and measured on various aspects of two systems. The two systems are selected and developed based on the same user requirements, development technologies, and methodologies. By comparing the two systems against the investigated metrics, we aim to reveal whether the dependency injection improve the code design. Then four test suites from both systems are evaluated in relation to testability. The results demonstrate that the dependency injection does not seem to improve the code design if comparing on the selected metrics. Even though it does not score better, its effect is evident in other software aspects. The testability of the two systems is similar and suffers from the same problem. Meanwhile, mock helps assist software testing and improve testability. The effect of mock technique can be witnessed, especially when it is applied with other test techniques. Explanations and discussions on these findings are addressed in the paper.

Feature Oriented Domain Specific Language For Dependency Injection In Dynamic Software Product LinesDayibas, Orcun 01 September 2009 (has links) (PDF)
Base commonality of the Software Product Line (SPL) Engineering processes is to analyze commonality and variability of the product family though, SPLE defines many various processes in different abstraction levels. In this thesis, a new approach to configure (according to requirements) components as building blocks of the architecture is proposed. The main objective of this approach is to support domain design and application design processes in SPL context. Configuring the products is made into a semi-automatic operation by defining a Domain Specific Language (DSL) which is built on top of domain and feature-component binding model notions. In order to accomplish this goal, dependencies of the components are extracted from the software by using the dependency injection method and these
dependencies are made definable in CASE tools which are developed in this work.

Rozšíření platformy pro analýzu datových toků o podporu knihoven na vkládání závislostí / Extending Data Lineage Analysis Platform with Support for Dependency Injection FrameworksRiedel, Lukáš January 2021 (has links)
Data lineage forms an important aspect of today's enterprise environment. MANTA Flow is a data lineage analysis platform that already has basic support for analysis of Java programs, provided by one of its components called Bytecode Scanner. Neverthe- less, there are very few applications in today's enterprise environment that do not use dependency injection at least in a very limited way. Therefore, we present an extension of Bytecode Scanner in the MANTA Flow platform to support data lineage analysis of dependency injection frameworks as well. The extension is able to process even complex definitions of standard dependency injection containers. Since the dependency injec- tion influences a selection of method call targets, we also provide a description of call graph structure and its modification to support dependency injection. Last, we use this infrastructure to design and implement a plugin into Bytecode Scanner for the Spring Framework, a popular dependency injection framework targeting Java Platform. The plugin has been successfully tested on a small but realistic software system that can read data from a file, transform them, and write them into a database. 1

Testdriven utveckling in action : Hur kan en organisation lyckas med testdriven utveckling?Lander, Magnus, Karlsson, Pracha, Mella, Daniel January 2014 (has links)
Inom en stor del av all systemutveckling sker testerna av systemet som sista punkt innan systemet sjösätts. Testdriven utveckling är en systemutvecklingsmetod där testerna istället skrivs först och också är det som driver utvecklingen framåt. Metoden höjs till skyarna av vissa och avfärdas omedelbart som onödigt omständig av andra. Vi vill med denna uppsats undersöka hur det ser ut i verkligheten och vilka faktorer som påverkar användandet, inlärningen och inställningen till testdriven utveckling. Vi genomförde intervjuer på tre stycken Örebrobaserade organisationer och tittade utifrån ramverket method-in-action på vilka faktorer som påverkade användningen och varför. Vi fann att utvecklarna närmade sig testdriven utveckling på väldigt olika sätt och grundade sin inställning mycket beroende på tidigare erfarenhet och inlärning – oavsett hur lång eller kort den varit. Utvecklarna förväntas ofta bedriva självstudier utanför arbetstid – något som inte alltid funkar som kunskaputvecklingsform då tiden utanför jobbet ser olika ut beroende på var i livet man är. Det finns inte heller något klart program eller best-practices att följa för att lära sig metoden i någon av organisationerna. Vi såg också att det finns tekniker utanför själva metoden som utvecklare ganska omgående behöver bli bekanta med för att kunna utveckla testdrivet: dependency injection och mock.

On Patterns for Refactoring Legacy C++ Code into a Testable State Using Inversion of ControlBöhlin, Per January 2010 (has links)
Amending old projects of legacy code to include agile practices such as extensive unit testing and refactoring has proven difficult. Since automated unit testing was not widely used a decade ago, much code has been written without unit testing in mind. This is especially true for C++ where RAII has been the dominant pattern .This has resulted in a lot of code that suffers from what best can be described as low testability. This also strongly impedes the creation of new unit tests to already existing code. Due to the lack of unit tests, refactoring is done sparsely and with great reluctance. This thesis work tries to remedy that and, in the scope of a limited case study on an existing code base, looks into different ways of creating and utilizing object seams in legacy C++ code to decouple dependencies to make isolated testing possible. This regards to: What are the impediments for code to be testable in an isolated setting? What are the steps for refactoring code to a testable state? The results can be summarized as to contain a list of factors affecting testability, among them: the use of asserts, global state, object instantiation, work in constructor and breaking Law of Demeter. Further with regards to patterns for refactoring code to a testable state, two types of patterns have crystallized: the injection of dependencies and the masking of dependencies using various techniques. The effect these two base patterns have on breaking dependencies on the base level and the Meta level is outlined. A catalogue of patterns has been compiled as part of the appendix. Inversion of Control (IoC) is a principle used to decoupling classes and since strong dependences is often an attribute giving grievances with regard to testability, it was a central concern in this thesis. IoC can be simplified from a developer standpoint with the help of frameworks or what is usually referred to as IoC containers. Two IoC containers for C++ were evaluated: Autumn Framework PocoCapsule In the evaluation of the two IoC containers it was concluded that Autumn was not mature enough as of the time of the evaluation to be used in production setting. PocoCapsule, even though compelling for some of its powerful features with regard to DSM and HOT, its configuration sometimes require in-code workarounds, affecting its usability in some set of scenarios. However, the big difference was with regard to how the two containers approaches configuration. PocoCapsule uses static analysis of its XML configuration file making it truly declarative while Autumn does runtime parsing and dynamic invocations resulting in a situation closer to procedural scripting.

Utvärdering och implementering av administrationsgränssnitt för säkerhets- och integrationsplattformen CESPBengtsson, Åke January 2011 (has links)
Cybercom Group AB har en kombinerad säkerhets- och integrationsplattform kallad CESP, Cybercom Enhanced Security Platform. I CESP finns bl.a. en autentiseringstjänst, åtkomstkontroll, loggning och logganalys. Det finns även ett webbaserat administrationsgränssnitt för att komma åt och administrera tjänsterna. Examensarbetet har gått ut på att utvärdera och omforma adminis-trationsgränssnittet för att göra gränssnittet mer enhetligt och lättarbetat. Examensarbetet har varit inriktat på att ge utvecklarna ett stöd för vidare utveckling med fokus på användbarhet och avslutades med en utvärdering mellan den »gamla« och »nya« administrationsportalen. Examensrapporten kommer ta upp hela arbetsprocessen indelat i dess fyra faser; undersökning, design, implementation och utvärdering. Examensarbetet har lett till en implementation av en begränsad del i en administrationsportal samt en omfattande pappersprototyp som visar hur en vidare implementation av administrationsportalen kan se ut. Resultatet av utvärderingen visade inte på någon signifikant skillnad mellan den »gamla« och »nya« administrationsportalen, detta till stor del p.g.a. felaktigt val av utvärderingsmetod som inte var lämpad att utvärdera två olika system.

Analyzing and Reducing Compilation Times for C++ ProgramsMivelli, Dennis January 2022 (has links)
Software companies often choose to develop in C++ because of the high performance that the language offers. Facilitated by static compilation and powerful optimization options, runtime performance is paid for with compilation time. Although the trade-off is inevitable to some extent, building very large C++ programs from scratch can take up to several hours if extra care is not taken during development. This thesis analyzes compilation times for C++ programs and shows how they can be reduced with the help of design patterns, implementation hiding, and framework related fixes. The results presented prove that compilation times can be decreased significantly with no drawbacks to the maintainability of a program. An in-depth analysis of compilation times and dependencies has been conducted for two large software modules from a representative company. Both modules take over an hour of CPU time each to compile. The time consumption for different compiler activities, such as parsing, preprocessing, and runtime optimization tasks have been measured for the modules. The compilation times for unit tests and mocks which use the GoogleTest framework have been analyzed. A simple method that may reduce compilation times by up to 50% for programs that use GoogleTest is presented. A dependency metric has been created, based on the number of include statements found recursively throughout a program. The dependency metric was found to be connected to compilation time for the two analyzed modules. Other factors that can influence compilation times are also shown, such as runtime optimization options, and the use of templates. Experiments which show how a typical usage of templates can drastically increase compilation times are presented. In addition, a solution which allows templates to be used while avoiding code bloat across translation units is reviewed. The solution effectively rivals non-template code in terms of compilation time. The Pointer to Implementation (PImpl) and Dependency Injection design patterns have been used to refactor a small program. Both design patterns performed well, reducing the total compilation time and total compiler memory usage by 70%. A program that detects dependency cycles has been created, but no cycles were found in any of two modules from the representative company.
