Slide 2 - What is Software Testing Software Testing is a method to check whether the actual software product matches expected requirements and to ensure that software product is bug free. It involves execution of software/system components using manual or automated tools to evaluate one or more properties of interest. The purpose of software testing is to identify errors, gaps or missing requirements in contrast to actual requirements. Some prefer saying Software testing definition as a White Box and Black Box Testing. In simple terms, Software Testing means the Verification of Application Under Test (AUT). This Software Testing course introduces testing software to the audience and justifies the importance of software testing.
Slide 3 - History of Software Testing Software testing is a process that helps ensure the quality of software products. It started alongside the development of software, which began just after World War II. Computer scientist Tom Kilburn is credited with writing the first piece of software, which was unveiled on June 21, 1948, at the University of Manchester in England. It performed mathematical calculations using machine code instructions. The development of software testing began shortly after the second world war when computer scientist Tom Kilburn created the first piece of software. This software debuted on June 21, 1948, at the University of Manchester in England and was able to perform mathematical calculations using machine code instructions.
Slide 4 - Types of Software Testing Manual vs. Automated Testing It's important to make the distinction between manual and automated tests. Manual testing is done in person, by clicking through the application or interacting with the software and APIs with the appropriate tooling. This is very expensive since it requires someone to setup an environment and execute the tests themselves, and it can be prone to human error as the tester might make typos or omit steps in the test script.
Slide 5 - Types of Tests Unit tests Integration tests Functional tests End-to-end tests Acceptance testing Performance testing Smoke testing
Slide 6 - Unit tests - Unit tests are very low level and close to the source of an application. They consist in testing individual methods and functions of the classes, components, or modules used by your software. Unit tests are generally quite cheap to automate and can run very quickly by a continuous integration server. Integration tests - Integration tests verify that different modules or services used by your application work well together. For example, it can be testing the interaction with the database or making sure that microservices work together as expected. These types of tests are more expensive to run as they require multiple parts of the application to be up and running. Functional tests - Functional tests focus on the business requirements of an application. They only verify the output of an action and do not check the intermediate states of the system when performing that action.
Slide 7 - End-to-end tests - End-to-end testing replicates a user behavior with the software in a complete application environment. It verifies that various user flows work as expected and can be as simple as loading a web page or logging in or much more complex scenarios verifying email notifications, online payments, etc... End-to-end tests are very useful, but they're expensive to perform and can be hard to maintain when they're automated. It is recommended to have a few key end-to-end tests and rely more on lower level types of testing (unit and integration tests) to be able to quickly identify breaking changes. Acceptance testing - Acceptance tests are formal tests that verify if a system satisfies business requirements. They require the entire application to be running while testing and focus on replicating user behaviors. But they can also go further and measure the performance of the system and reject changes if certain goals are not met.
Slide 8 - Performance testing - Performance tests evaluate how a system performs under a particular workload. These tests help to measure the reliability, speed, scalability, and responsiveness of an application. For instance, a performance test can observe response times when executing a high number of requests, or determine how a system behaves with a significant amount of data. It can determine if an application meets performance requirements, locate bottlenecks, measure stability during peak traffic, and more. Smoke testing - Smoke tests are basic tests that check the basic functionality of an application. They are meant to be quick to execute, and their goal is to give you the assurance that the major features of your system are working as expected. Smoke tests can be useful right after a new build is made to decide whether or not you can run more expensive tests, or right after a deployment to make sure that they application is running properly in the newly deployed environment.
Slide 9 - Why Software Testing is Important Software testing is an important aspect of software development that cannot be overlooked. Late software delivery or defects can ruin a company's reputation with customers, leading to frustration and a loss of business. In some cases, a bug or system defect can cause major malfunctions or damage other interconnected systems.
