Automated Testing

Manual or Automated Testing for Your Software?

No matter how skilled your Ruby, JavaScript, or PHP programmer maybe, they WILL make mistakes. Mistakes are unfortunately inevitable, especially if the application you are writing is highly complex. To ensure that these mistakes do not get through to the customer however, your development team will employ some form of testing.

The problem with this is however that testing is not really adding any value to the product, it can be time-consuming and thus expensive. It can also cause significant delays to your project if the coders have to wait while the tests are completed before they are able to continue with their work.

Manual testing takes time, often a huge amount of time. Imagine if you have a piece of software with multiple forms to fill in. Each form has multiple fields for information. It could take several minutes to simply complete each form and see if the information is accepted. Then you need to check that the information is actually being used and stored the way that it should be. If you discover a fault and feed it back to the team, you will then need to repeat this test all over again to see if the issue has been truly fixed or if it has triggered other issues. Imagine again, having to do these tests repeatedly as each revision is made to the software. Not only will it be time-consuming it will also be boring.

Boring work makes mistakes. Entrusting people to check for errors is never going to be infallible. People overlook things and make mistakes of their own. No matter how good your QA team is, there will always be times that they themselves will make mistakes.

You will want your testing to be done as quickly as possible while also delivering accurate results. You will also want those tests to be wholly repeatable so that they can be rerun and compared to previous results as your PHP development team revise and build your software.

Thankfully, just as you can write an app to deliver the functionality that your customers are looking for, you can also build software to test that software. Automated software testing can help you to get your testing done in a more repeatable and quicker manner.

However, for small companies, there is often a reluctance to invest in automated testing. The reason for this is that it will cost you money upfront to develop the tools that you need for the task. While this may be the case, for most projects this initial investment in time and money will be recouped many times over.

How Can Automated Testing Improve Performance and Efficiency?

In any Agile team, you will be looking to gain feedback as quickly as possible. Using manual testing, however, can cause you significant delays and one easy way around this is to introduce automated testing of your software.

When hiring PHP programmer talent you will want to check their preference with regards to manual and automatic testing. Many can be highly biased as to what they prefer and you need to ensure that you provide what is best for your project. You also have to consider beyond the initial project if the app that is to be designed is likely to grow and be revised in the future.

As with any decision your PHP programmer needs to make a decision based on the likely return on investment. Designing a piece of automated testing software will cost money and take time in itself. But you need to weigh this against the time and money saved later within the project. Often automated tools can do the work that would take days to do manually in a matter of hours or even minutes.

So what are the realities of automated testing? How can it really help you? The following are just a few of the significant benefits of using software to test software:

Should You Be Using Automated Testing or Manual Methods?

Automated testing offers many benefits over manual testing. However, it does not mean that you should completely stop your manual testing. Often issues come to light when someone does something out of the norm with the software, something that a highly repetitive piece of test software simply will not do.

Software is perfect for testing when you want to run data through your app to see that it works as it should. However, that software still needs to be designed and will only do what is asked of it. If it is poorly designed at the start then it may not provide you with the protection that you are looking for with your project.

Automated testing is always the best choice if you are going to be conducting a large volume of repetitive tests on a regular basis. Especially if those tests will need to be repeated on different platforms and configurations. It is also best if you will need to enter large data sets and for testing, that would simply be impossible for you to do manually.

Always do your homework at the start, you will often find that the return on your investment in setting up automatic software testing will be significant when compared to running the tests manually. That is without taking into account the many other benefits that it offers such as repeatability and accuracy.
