Why You Need Software Testing

To answer the question posed in the title , we have to understand what is software testing . In fact , consists of two components:
  • Verification: are we building / doing the right thing ?
  • Validation: are we building / doing things right ?
Verification allows us to be sure we understand what you want to achieve, and validation ensures that we have parties that , in addition to being well implemented . This is not only applicable to software development , or, as discussed below .Do you need to do software testing?If you are running a project involving computers, then you will have to do some testing of software. In the simplest point of interaction , this could be sure a piece of software that does what you want ( test requirements ) before rolling out across the company.For commissioning software actively believed (either a simple implementation of a Wordpress blog or an application) , software testing becomes an important milestone in the plan. Software developers should not be trusted out all aspects of software testing , but at the same time is the responsibility of the implementation of the software to ensure that their needs are accurate.You can not blame a developer for the delivery of something that does not meet , if requirements are unclear or incomplete. This is the first stage of the test .

When ( in the project) should be performed software testing?Software testing should be performed as soon as possible . Promoting agile techniques that result in early delivery (though incomplete) software packages allows testing to start on time course corrections can be made in a relatively low cost .The afternoon that these same corrections are needed , the more it costs . The most expensive time to fix a product when it's finished - unfortunately , many people believe in letting software testing to the end of the project , contributing to the statistics of failures in software development projects .When ( development ) should be tested software ?Again, the answer to this is easy to say - as soon as possible .As a developer ( programmer / writer), it is your responsibility to deliver bug-free software . Now , this is not always possible due to time and / or budget constraints , but should be the goal .To achieve this , testing of each piece of code should be conducted separately , and to do that, you need to know what should be the result (expected result ) to run the code under various conditions. This, in turn , is based on a design background and properly tested .
Therefore, the test needs to start as soon as possible - in the design stage - and continues through integration testing .All this is valid for other projects , too:
  • Needs testing : is it really the website, report , results app / application you want ?
  • Component Testing : Of all the various parts that are selected / created to do what we expect ?
  • integration testing : not all components work together properly ?
  • Stress testing / performance: is scalable ?
These four aspects of software testing are as applicable to the development of an application, web service or product independent shrink as they are for something as seemingly disparate as building a house, so a Formula 1 car or operating a store.Evidence, then, is not just for software, but software testing is increasingly vital in modern projects as computers continue to take care of many aspects of working life .
