1. What is testing?

Have you ever wondered what is test? Testing is between us everyday, when we wake up, when we go to work or even the act of opening a door. Does that work? how long it will last? Those are common questions that sellers needs to answer when costumers are buying any product.

And how to find the correct answer? Well, in the product example is simple. The first step is to submit the product through a series of tests, such as the material resistance, durability, life time and so on.

  1. the means by which the presence, quality, or genuineness of anything is determined; a means of trial.
  2. the trial of the quality of something: to put to the test.
  3. a particular process or method for trying or assessing.

The essence of a test is simply to guarantee that a given element does what it supposed to do, not more or less just what it needs to do.

In software development is the same, software out there need to go through a battery of tests to make sure that the software works in different environments, different programming language versions or even different browsers if we are talking about web software(could be different devices to mobile software).

Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects), and to verify that the software product is fit for use.

Often the testing part is done by a QA(Quality Assurance) area, the purpose is guarantee the quality of the software before submit to the client.
