Best software testing services will make all the difference between successful and unsuccessful SaaS products. A program with features very similar to other people can be a success given it functions nicely without problems and makes the user feel happy using it. Your testing procedure can make or break the program; make sure that this aspect is cared for by a team of expert persons.
Whether you're doing QA for your SaaS application on your own company or give it to a renowned software testing services, there's some vital kind of tests that needs to be carried out. They're enlisted below:
A map of the several kinds of testing
This is the most elementary type of testing, in which the application gets categorized into different parts, and then each is checked separately. For instance, let's take the case of a vehicle tracking application. The app will be divided into all the different modules, like reports, geographical location, driver details, hunt, etc..
Here you assess whether different elements of the system, when integrated together, function correctly. From the monitoring application, we'll test whether the customer receives a message once the payment is due (integration with SMS gateway and email server), be in a position to perform the payment within the program, can fetch information from third-party sources using API's, etc..
Here you assess how the whole application works. That is exactly what the end-user will face, which you'll know about. Even if operational and integration test cases were passed, you are going to have to make sure it works together as expected, in the system.
This one checks whether the system can take a growing load of several users. Your automobile tracking application might be working correctly when there's one truck to be monitored. What when there are 100? The system may crash if regression testing isn't done. This kind of testing does, it creates many virtual users and then assesses whether the machine can take care of all of them without impacting the program speed.
Alright, your application met each of the checkpoints. Imagine if a couple of months following the launch, a hacker stole all of the passwords and sensitive information? This actually happens because expecting a hacker not to steal your data since you didn't harm, is like expecting a tiger not to attack you because you're a vegan. There are numerous things like cross-site scripting, SQL injection, database layouts, etc. which developers usually don't take of when making the program. For data-sensitive applications, it's highly suggested to find safety testing completed.
It is suggested to automate this procedure by using tools like Rational AppScan or even Apache JMeter, which will create scripts and then you are able to conduct the tests. It saves a lot of effort and time in the long run.
