Web Application Testing

The main goal for any developer of web services and web applications is to create reliable, safe, high-quality, accessible resources for potential users. At the same time, one of the key stages of this work is comprehensive professional testing of these products, i.e. identifying and fixing bugs, checking the completeness of functionality, testing for security and convenience.

Why It Is Necessary to Test Web Applications and Web Services

The quality of all the products created by the developer depends on how well the testing of web services and web applications is conducted, including testing of performance, functionality, application security, and vulnerability of the web server used in a particular application. Errors in web services operation can result not only in competitive disadvantages, but also in more disastrous consequences:

  • Financial losses by the users (most famous cases are large scale money thefts through cryptocurrency exchange);
  • Personal data leaks (a very sensitive topic, especially considering that such leaks can be caused by some errors in the product, but not by hackers’ activity);
  • Incorrect service operation (leads to the loss of the service value for the users).

Types and Stages of Web App and Web Server Testing

We use a variety of testing types and methods to test web applications and web servers:

  • Functional testing. In the checklists for this type of testing, we set the following goals: detect errors in the work of external and internal links, verify proper functions of the user input forms (correct validation for each field of the form), evaluate the security of cookies, identify possible errors in HTML code and check if the application correctly interacts with the database;
  • Test for ease of application use (Usability testing). This verification step involves searching for bugs that reduce the application usability level, for instance, make main menu inaccessible, impede navigation, and make a negative impact on the web application in general;
  • Server security check (Vulnerability testing). At this testing stage, we check the reliability of the web servers used by the applications via sending specific commands to the servers and analyzing the received responses. Sending incorrect requests allows finding links to incorrectly operating versions of the servers;
  • Web application security check consists in searching for a possible attack vector and is carried out using automated scanning and manual testing (pen-testing). Additionally, to identify bugs, we apply potential password cracking, network scanning and virus scanning methods;
  • Application user interface test (UI testing) involves verifying graphic design accuracy, as well as the application clarity, convenience and user-friendliness. Also, at this stage, we test server compatibility with the database and software being used;
  • Application compatibility check (Configuration testing) is used to detect bugs in web applications operating in various types of browsers with cross-browser slicing. In addition, we detect errors which occur when the applications are launched in various operating systems or viewed on mobile devices;
  • Load testing (Performance check) includes verifying the correct operation of applications and servers under peak and stress loads, and identifying the dependence of the applications download speed, uninterrupted operation and data availability on the number of concurrent application users.

The above mentioned main and auxiliary techniques of web application and web servers testing allow our specialists to test most complex projects quickly and effectively, and our customers – to achieve an increase in demand for the products they develop.
