Core Elements of Continuous Testing
WHITE PAPER CORE ELEMENTS OF CONTINUOUS TESTING Today’s modern development disciplines -- whether Agile, Continuous Integration (CI) or Continuous Delivery (CD) -- have completely transformed how teams develop and deliver applications. Companies that need to compete in today’s fast-paced digital economy must also transform how they test. Successful teams know the secret sauce to delivering high quality digital experiences fast is continuous testing. This paper will define continuous testing, explain what it is, why it’s important, and the core elements and tactical changes development and QA teams need to make in order to succeed at this emerging practice. TABLE OF CONTENTS 3 What is Continuous Testing? 6 Tactical Engineering Considerations 3 Why Continuous Testing? 7 Benefits of Continuous Testing 4 Core Elements of Continuous Testing WHAT IS CONTINUOUS TESTING? Continuous testing is the practice of executing automated tests throughout the software development cycle. It’s more than just automated testing; it’s applying the right level of automation at each stage in the development process. Unlike legacy testing methods that occur at the end of the development cycle, continuous testing occurs at multiple stages, including development, integration, pre-release, and in production. Continuous testing ensures that bugs are caught and fixed far earlier in the development process, improving overall quality while saving significant time and money. WHY CONTINUOUS TESTING? Continuous testing is a critical requirement for organizations that are shifting left towards CI or CD, both modern development practices that ensure faster time to market. When automated testing is coupled with a CI server, tests can instantly be kicked off with every build, and alerts with passing or failing test results can be delivered directly to the development team in real time. -
Studying the Feasibility and Importance of Software Testing: an Analysis
Dr. S.S.Riaz Ahamed / Internatinal Journal of Engineering Science and Technology Vol.1(3), 2009, 119-128 STUDYING THE FEASIBILITY AND IMPORTANCE OF SOFTWARE TESTING: AN ANALYSIS Dr.S.S.Riaz Ahamed Principal, Sathak Institute of Technology, Ramanathapuram,India. Email:[email protected], [email protected] ABSTRACT Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. Software testing is the process of testing the functionality and correctness of software by running it. Software testing is usually performed for one of two reasons: defect detection, and reliability estimation. The problem of applying software testing to defect detection is that software can only suggest the presence of flaws, not their absence (unless the testing is exhaustive). The problem of applying software testing to reliability estimation is that the input distribution used for selecting test cases may be flawed. The key to software testing is trying to find the modes of failure - something that requires exhaustively testing the code on all possible inputs. Software Testing, depending on the testing method employed, can be implemented at any time in the development process. Keywords: verification and validation (V & V) 1 INTRODUCTION Testing is a set of activities that could be planned ahead and conducted systematically. The main objective of testing is to find an error by executing a program. The objective of testing is to check whether the designed software meets the customer specification. The Testing should fulfill the following criteria: ¾ Test should begin at the module level and work “outward” toward the integration of the entire computer based system. -

Leading Practice: Test Strategy and Approach in Agile Projects
CA SERVICES | LEADING PRACTICE Leading Practice: Test Strategy and Approach in Agile Projects Abstract This document provides best practices on how to strategize testing CA Project and Portfolio Management (CA PPM) in an agile project. The document does not include specific test cases; the list of test cases and steps for each test case are provided in a separate document. This document should be used by the agile project team that is planning the testing activities, and by end users who perform user acceptance testing (UAT). Concepts Concept Description Test Approach Defines testing strategy, roles and responsibilities of various team members, and test types. Testing Environments Outlines which testing is carried out in which environment. Testing Automation and Tools Addresses test management and automation tools required for test execution. Risk Analysis Defines the approach for risk identification and plans to mitigate risks as well as a contingency plan. Test Planning and Execution Defines the approach to plan the test cases, test scripts, and execution. Review and Approval Lists individuals who should review, approve and sign off on test results. Test Approach The test approach defines testing strategy, roles and responsibilities of various team members, and the test types. The first step is to define the testing strategy. It should describe how and when the testing will be conducted, who will do the testing, the type of testing being conducted, features being tested, environment(s) where the testing takes place, what testing tools are used, and how are defects tracked and managed. The testing strategy should be prepared by the agile core team. -
Functional Testing Functional Testing
From Pressman, “Software Engineering – a practitionerʼs approach”, Chapter 14 and Pezze + Young, “Software Testing and Analysis”, Chapters 10-11 Today, weʼll talk about testing – how to test software. The question is: How do we design tests? And weʼll start with Functional Testing functional testing. Software Engineering Andreas Zeller • Saarland University 1 Functional testing is also called “black- box” testing, because we see the program as a black box – that is, we ignore how it is being written 2 in contrast to structural or “white-box” testing, where the program is the base. 3 If the program is not the base, then what is? Simple: itʼs the specification. 4 If the program is not the base, then what is? Simple: itʼs the specification. Testing Tactics Functional Structural “black box” “white box” • Tests based on spec • Tests based on code • Test covers as much • Test covers as much specified behavior implemented behavior as possible as possible 5 Why Functional? Functional Structural “black box” “white box” • Program code not necessary • Early functional test design has benefits reveals spec problems • assesses testability • gives additional explanation of spec • may even serve as spec, as in XP 6 Structural testing can not detect that some required feature is missing in the code Why Functional? Functional testing applies at all granularity levels (in contrast to structural testing, which only applies to Functional Structural unit and integration testing) “black box” “white box” • Best for missing logic defects Common problem: Some program logic was simply forgotten Structural testing would not focus on code that is not there • Applies at all granularity levels unit tests • integration tests • system tests • regression tests 7 2,510,588,971 years, 32 days, and 20 hours to be precise. -

These bottlenecks include finding and setting up test environments, test configurations, and test results implementation. These issues are not industry specific. They can be experienced in manufacturing, service businesses, and governments alike. They can be reduced by having a thorough understanding and a disciplined, mature implementation of Continuous Testing and related recommended engineering practices. The best place to start addressing these challenges is having a good understanding of what Continuous Testing is. Marc Hornbeek, the author of Engineering DevOps, describes it as: “A quality assessment strategy in which most tests are automated and integrated as a core and essential part of DevOps. Continuous Testing is much more than simply ‘automating tests.’” In this whitepaper, we’ll address the best practices you can adopt for implementing Continuous Quality and Testing on the AWS Cloud environment in the context of the DevOps model. -

Component System Typical intercomponent interfaces (locus of (Focus of Integration) (Scope of integration faults) Integration) Method Class Instance variables Intraclass messages Class Cluster Intraclass messages Cluster Subsystem Interclass messages Interpackage messages Subsystem System Inteprocess communication Remote procedure call ORB services, OS services -Integration test design is concerned with several primary questions: 1. Which components and interfaces should be exercised? 2. In what sequence will component interfaces be exercised? 2 3. Which test design technique should be used to exercise each interface? -Integration testing is a search for component faults that cause intercomponent failures. -System scope testing is a search for faults that lead to a failure to meet a system scope responsibility. ÷System scope testing cannot be done unless components interoperate sufficiently well to exercise system scope responsibilities. -Effective testing at system scope requires a concrete and testable system-level specification. ÷System test cases must be derived from some kind of functional specification. Traditionally, user documentation, product literature, line-item narrative requirements, and system scope models have been used. 3 2. Integration Testing -Unit testing focuses on individual components. Once faults in each component have been removed and the test cases do not reveal any new fault, components are ready to be integrated into larger subsystems. -Integration testing detects faults that have not been detected during unit testing, by focusing on small groups of components.
