Rapid cycle testing software

The commonly used software testing strategies are listed below. A testing strategy should be developed with the intent to provide the most effective and efficient way of testing the software. While developing a testing strategy, some questions arise such as: when and what type of testing is to be done?

What are the objectives of testing? Who is responsible for performing testing? What outputs are produced as a result of testing?

The inputs that should be available while developing a testing strategy are listed below. The output produced by the software testing strategy includes a detailed document, which indicates the entire test plan including all test cases used during the testing phase. A bug can go undetected until a failure occurs, which is when a user or tester perceives that the system is not delivering the expected service.

In the system test phase, the goal of the test engineer is to induce failures through testing and thereby uncover and document the associated bugs so they can be removed from the system.

Ideally the life of a bug ends when it is uncovered in static or dynamic testing and fixed. One practical consequence of the definition of testing is that test engineers and development engineers need to take fundamentally different approaches to their jobs. The goal of the developer is to create bug-free code that satisfies the software design and meets the customer's requirements.

The developer is trying to "make" code. The goal of the tester is to analyze or operate the code to expose the bugs that are latent in the code as it is integrated, configured, and run in different environments.

The tester is trying to "break" the code. In this context, a good result of a software test for a developer is a pass, but for that same test a successful outcome for the test engineer is a fail.

Ultimately, of course, both the developer and tester want the same thing: a product that works well enough to satisfy their customers. There are two basic functions of software testing: one is verification and the other is validation. Verification is the assurance that the products of a particular phase in the development process are consistent with the requirements of that phase and the preceding phase.

The purpose of validation is to ensure that the system has implemented all requirements, so that each function can be traced back to a particular customer requirement. In other words, validation makes sure that the right product is being built.

Verification is focused more on the activities of a particular phase of the development process. For example, one of the purposes of system testing is to give assurance that the system design is consistent with the requirements that were used as an input to the system design phase. Unit and integration testing can be used to verify that the program design is consistent with the system design.

In simple terms, verification makes sure that the product is being built right. We'll see examples of both verification and validation activities as we examine each phase of the development process in later chapters. One additional concept that needs to be defined is quality. Like beauty, quality is subjective and can be difficult to define.

We will define software quality in terms of three factors: failures in the field, reliability, and customer satisfaction. A software product is said to have good quality if:. It has few failures when used by the customer, indicating that few bugs have escaped to the field.

It is reliable, meaning that it seldom crashes or demonstrates unexpected behavior when used in the customer environment. One implication of this definition of quality is that the test group must not only take measures to prevent and detect defects during product development, but also needs to be concerned with the reliability and usability of the product.
