software testing is necessary to make sure the product or application is defect free, as per customer specifications. Software testing identifies fault whose removal increases the software Quality and Increases the software reliability.Testing effort is directly proportional to the complexity of the program.
This is the chapter 3 of ISTQB Agile Tester Extension certification. This presentation helps aspirants understand and prepare content of certification.
Tool Support for Testing as Chapter 6 of ISTQB Foundation 2018. Topics covered are Tool Benefits, Test Tool Classification, Benefits of Test Automation, Risk of Test Automation, Selecting a tool for Organization, Pilot Project, Success factor for using a tool
Unit testing is a method to test individual units of source code to determine if they are fit for use. A unit is the smallest testable part of an application. Unit tests are created by programmers during development. Test-driven development uses tests to drive the design by writing a failing test first, then code to pass the test, and refactoring the code. Unit tests should be isolated, repeatable, fast, self-documenting, and use techniques like dependency injection and mocking dependencies. Benefits of unit testing include instant feedback, promoting modularity, acting as a safety net for changes, and providing documentation.
This document provides an introduction to unit testing and mocking. It discusses the benefits of unit testing such as safer refactoring and value that increases over time. It provides a recipe for setting up a unit test project with test classes and methods using AAA syntax. It also covers what mocking is and how to use mocking frameworks to create fake dependencies and check interactions. Resources for learning more about unit testing and related tools are provided.
This document discusses software engineering and software testing. Software engineering is concerned with developing large software through applying engineering principles. The challenge is to produce high quality software within budget and schedule constraints. Software testing is the process of finding errors in software and involves both manual and automated testing. Different types of testing include unit, integration, system, and acceptance testing. The goal of testing is to uncover defects early and reduce costs.
This is my complete introductory course for Software Test Automation.If you need full training that includes different automation tools (Selenium, J-Meter, Burp, SOAP UI etc), feel free to contact me by email ([email protected]) or by mobile (+201223600207).
Chapter 1 of ISTQB Agile tester extension certification. This chapter will give you the understanding about the content of chapter 1 of the certification.
Testing involves finding errors in a program. The goal is to assume a program contains errors and test to find as many as possible. Different testing techniques include white box testing by developers and black box testing by testers. Testing levels include unit, integration, system, and user acceptance testing. Developers and testers have different goals - developers want code to work while testers try to make code fail. Good development practices from a tester's view include doing own acceptance tests, fixing bugs, writing helpful error messages, and not artificially adding bugs. Good relationships between project managers, developers and testers help ensure quality.
This document provides an overview of agile testing. It discusses what agile testing is, common agile testing strategies and stages, principles of agile testing, advantages such as reduced time and money and regular feedback, challenges like compressed testing cycles and minimal time for planning, and concludes that communication between teams is key to agile testing success. The agile testing life cycle involves four stages: iteration 0 for initial setup, construction iterations for ongoing testing, release for deployment, and production for maintenance. Principles include testing moving the project forward, testing as a continuous activity, everyone on the team participating in testing, and reducing feedback loops.

Gherkin is a business readable language used to write automated acceptance tests in a format called scenarios. Scenarios use keywords like Given, When, Then to describe a system's behavior in a way that both technical and non-technical team members can understand. Cucumber is a tool that reads Gherkin files and runs acceptance tests. The Gherkin syntax and Cucumber tool support a behavior-driven development process where tests are written before code using a collaborative approach between developers, testers, and business stakeholders.

Unit Testing Concepts and Best PracticesDerek Smith
Unit testing involves writing code to test individual units or components of an application to ensure they perform as expected. The document discusses best practices for unit testing including writing atomic, consistent, self-descriptive tests with clear assertions. Tests should be separated by business module and type and not include conditional logic, loops, or exception handling. Production code should be isolated from test code. The goal of unit testing is to validate that code meets specifications and prevents regressions over time.
The document provides an overview of code coverage as a white-box testing technique. It discusses various coverage metrics like statement coverage, decision coverage, conditional coverage, and path coverage. It also covers code coverage implementation in real tools and general recommendations around code coverage goals and testing practices. The presentation includes demos of different coverage metrics and aims to help readers learn about coverage theory, metrics, and tools to familiarize them with code coverage.
Cypress is an e2e testing tool that allows for testing web applications directly in the browser. It provides native access to the browser without using Selenium, making tasks like taking screenshots and recording videos possible. Some limitations are that it only supports single-page applications and one browser tab at a time. Cypress prioritizes developer experience through features like fast testing, intuitive debugging, and integration with continuous integration systems and dashboards. Many large companies have adopted Cypress for their e2e testing needs.
Client side unit tests - using jasmine & karmaAdam Klein
This document discusses client-side testing using Jasmine and Karma. It introduces Jasmine as the most popular testing framework for writing unit tests in the browser. It demonstrates a simple example of using Jasmine to test a Person constructor function. It then discusses Karma, a test runner that makes browser testing seamless. Karma allows running tests across multiple browsers simultaneously. The document also covers techniques for testing AngularJS controllers and services, including mocking external server calls. It emphasizes that while tests may pass using mocks, the mocks represent the contract with the external code being tested.
This document discusses JavaScript unit testing and introduces the QUnit testing framework. It demonstrates how to write testable code, set up a basic testing file with QUnit, and run tests to validate code works as expected across browsers. Automating testing with tools like Phing is also presented to speed the testing process without using a browser. Cross-browser testing challenges are noted along with alternatives to browser-based testing for greater speed.

Unit Testing, TDD and the Walking SkeletonSeb Rose
The document discusses unit testing, test-driven development (TDD), and the walking skeleton approach. It provides an overview of these software development practices, including writing automated tests before code, using the tests to drive code development, and starting projects with an initial architecture or "walking skeleton" that is automatically testable, buildable, and deployable. The document aims to dispel common myths about testing and convince readers of the value of these practices.
This document discusses Test Driven Development (TDD). It defines TDD, outlines the TDD process which involves writing tests first and then code to pass the tests, and emphasizes refactoring. Benefits of TDD include improved code quality, reduced bugs, and serving as documentation. Key TDD terms and libraries like JUnit and Mockito are explained. Continuous Integration (CI) is also discussed as it automates testing and builds when code is committed.
Test-driven development (TDD) is a software development process that relies on the repetition of short development cycles called red-green-refactor cycles. In TDD, tests are written before code to define desired functionality, and then code is written to pass those tests; this is followed by refactoring. The benefits of TDD include producing code that is robust, well-designed, and with fewer bugs due to comprehensive test coverage. While TDD requires discipline, it helps ensure code works as intended and allows refactoring with confidence that changes don't break existing functionality. Some potential vulnerabilities of TDD are that it may not prevent wrong solutions if requirements are unclear, can be difficult for UI or database-dependent programs
Unit testing tests individual units of source code to determine if they are fit for use. It is different from integration testing, which combines modules, and validation testing, which checks that a system meets specifications. The goal of unit testing is to isolate and test each part of a program to show that individual parts are correct. Unit testing provides benefits such as finding problems early, facilitating automated testing and change, and improving software quality. Guidelines for effective unit testing include knowing the objective of each test, making tests self-sufficient, ensuring tests are deterministic, following naming conventions, duplicating code for readability, testing results not implementation, and using isolation frameworks.
Test Driven Development (TDD) is a software testing methodology where developers write automated test cases before writing any code. It involves writing a failing test case for new functionality, then writing the minimum amount of code to pass that test, and refactoring the code. Key steps are to add a test, run all tests and see the new one fail, write code to pass the test, run tests to succeed, and refactor code while maintaining tests. Benefits include instant feedback, better code quality, and lower rework effort. Limitations include difficulty testing certain types of code like GUIs. Unit testing tests individual units of code in isolation through mocking of external dependencies.
Test-driven development (TDD) is a software development technique where unit tests are written before code to define desired functionality. Writing tests first helps produce code with better design, lower maintenance costs, and fewer bugs. Key principles of TDD include writing code only to pass failing tests and eliminating duplication. Benefits include better test coverage, easier refactoring, and preventing regressions. TDD helps developers act as users to define behavior through interactions between system components.
The document outlines chapters from a book on developer testing. It discusses working in cross-functional teams and the roles of developers and testers. Developers are responsible for unit testing and some integration testing, while other types of testing like security and performance are usually not done by developers. The document also discusses testing terminology, styles, objectives, and what makes software testable from a developer's perspective. Testability brings benefits like being able to easily verify functionality and make changes without surprises.
The document introduces unit testing to management and business stakeholders, explaining that unit tests are written by developers to test their code, catch errors early in the development process when they are cheaper to fix, and ensure code works as intended as well as provide many other benefits like establishing a safety net and writing cleaner code. Unit tests should be implemented throughout the software development lifecycle from initial coding through integration and regression testing.
Ever tried doing Test First Test Driven Development? Ever failed? TDD is not easy to get right. Here's some practical advice on doing BDD and TDD correctly. This presentation attempts to explain to you why, what, and how you should test, tell you about the FIRST principles of tests, the connections of unit testing and the SOLID principles, writing testable code, test doubles, the AAA of unit testing, and some practical ideas about structuring tests.
Unit testing involves testing individual units or components of code to ensure they work as intended. It focuses on testing small, isolated units of code to check functionality and edge cases. Benefits include faster debugging, development and regression testing. Guidelines for effective unit testing include keeping tests small, automated, independent and focused on the code's public API. Tests should cover a variety of inputs including boundaries and error conditions.
The document discusses unit testing and test-driven development (TDD). It provides an overview and agenda for the topics, including definitions of unit testing and TDD. It addresses common misconceptions about unit testing and TDD. Benefits of unit testing include making code easier to maintain and understand through automated testing. TDD helps with understanding problems and designing code with test coverage. The document emphasizes the importance of writing good, trustworthy, and maintainable unit tests.
This was a workshop given on the UTN University, for the Software Engineering students. The idea is to give a brief explanation about TDD, and how to use it.
The document outlines an upcoming programming workshop that will cover various JetBrains IDEs like PyCharm, IntelliJ IDEA, and PhpStorm. It then discusses Test Driven Development (TDD), including what TDD is, the development cycle used in TDD, and benefits like encouraging simple designs and confidence. Different types of software tests are also listed like unit tests, integration tests, acceptance tests, and others. Specific testing techniques like unit testing, integration testing using bottom-up and top-down approaches, and acceptance testing are then explained at a high level. Finally, some important notes on testing like trusting tests and prioritizing maintainability are provided.
Keyword-driven testing is a software testing methodology that uses predefined keywords to describe test cases instead of natural language. Keywords represent common testing actions and are associated with code that implements those actions. This allows testers to write automated test cases without extensive programming knowledge. The document discusses how to implement keyword-driven testing using the Maveryx test automation tool, including identifying keywords, writing test cases with keywords, implementing keyword code, and executing automated tests.

3. What is unit testing?
A unit test is an automated piece of code
that invokes a unit of work in the system and
then checks a single assumption about the
behavior of that unit of work.
4. What is unit testing?
A unit of work is a single logical functional
use case in the system that can be invoked by
some public interface (in most cases).
A unit of work can span a single method, a
whole class or multiple classes working together
to achieve one single logical purpose that can be
verified.
8. Why we need unit testing?
Highly stable solution
Integration of different components will be easier
New and regression defects can be minimized
Good unit testing reduces the test cycle for each
phrase
Good unit testing can be a good reference for the
system documentation
10. Test-Driven Development
Write test cases for a specific part of your code
Write your code to ‘fill in’ the tests. Your code only
serves to make all of your tests pass, and nothing
more
Once all your tests pass, go back and clean your
code (Refactoring)
TDD gives developers the power to think clearly about
the specifications before they engage themselves with
implementations.
11. Test-Driven Development
Writing a failing test case
Run the test,
Fail?
Write application code
Run the tests,
Success?
Refactor

12. Behavior-Driven Development
Write application code first.
Test cases must be small and tests one thing. Test a small
unit of code instead of the entire application
Run test cases against class or method specific for that
test case
If test fails, fix the defects and test again
With BDD, you can write specifications that are small and easy
to read.
13. Behavior-Driven Development
Write class(es) or method(s)
Write unit tests

15. What is Jasmine?
Jasmine is a behavior-driven testing
framework for JavaScript programming language.
It does not depend on any other JavaScript
frameworks. It does not require a DOM.
