Functional Testing

Type of quality assurance for websites that considers previously specified software behaviour, based on system specification. Its most serious advantage exists in the simulation of actual website application. Functions are tested by feeding them input and examining the output, while internal program structure is rarely considered. Functional testing usually describes what the system does.

Maintenance Testing

Testing type which is performed on the software during enhancement, change, or a migration cycle to other hardware. Testing is done on software that is already deployed. Maintenance testing may be divided into two types:

Confirmation testing. Performed in order to ensure that bugs and errors that were found previously are fixed. Whidegroup experts will help you to identify site’s potential bugs and errors to prevent significant losses. Wherever you customers live - UK, EU, Australia, Canada or USA - all of them will be pleased by your service.

Regression testing. Collective name of all testing kinds intended to detect an error in already tested code snippets. This testing type which verifies that previously developed and tested software still performs without errors after it was changed.

Performance Testing

One of the most important steps in website quality control testing, it gives an impression on how a website will react to a load with a specified number of visitors. The use of this test site improvement excludes the possibility of site overload and guarantees uninterrupted work during peak loads.

Usability Testing

Carried out in order to demonstrate the ease of use of user interface. It determines whether the application or the product built is user-friendly. It is divided into two types:

User interface testing. During this step, product is checked in according compliance with the requirements of practicality for users. The main goal is to evaluate how convenient the interface is, including navigation effectiveness and the degree of information perception by user. After analysing the users’ impressions, engineers adjust details.

Cross-platform testing. Specialized testing type that allows the determination of product behaviour in various environments to verify its suitability to work on multiple platforms. In its use, the platform can include various OSs and devices that will be necessary to run your solution. Cross-platform testing also includes cross-device testing.

Code Review and
Quality Analysis

Systematic software source-code review in order to detect and fix errors, which went unnoticed in the initial development phase. The main goal of this review is software quality improvement.

Compatibility Testing

Software testing type used to ensure product compatibility with various other objects such as web browsers, platforms, users (in cases of very specific requirement types, e.g. user who speaks and reads in only a particular language), Oss, etc. This testing type helps ascertain how successful the system performs in a particular environment that includes the hardware, network, OS, and other software, etc.

Website Security Testing

Assess vulnerability of software to various attacks types. Computer systems are often targets for trespassing/illegal penetration. Trespassing includes a wide range of actions, from hackers’ attempts to penetrate a system just for fun, to more nefarious hacks by rogues desiring illegal gain.

Ultimately, there is no real difference as to what functional area of testing is used for testing performance, as all of them are tuned according to the requirements of each certain project, and as a result some conclusive approach will form. It helps to apply testing techniques and methods according to the project type and needs, thus leading the project to its goals and increase its quality. I.e., e-commerce quality assurance - for e-commerce projects, etc.

How we help our clients

Problem

Solution

Problem

Website outputs an internal server error.

Solution

Most common internal server error causes are .htaccess-file wrong structure and improper handling with CGI-scripts. We fix errors in .htaccess-file and adjust its structure according to your needs.
As for CGI-scripts, we offer the following solutions:

recording right tuning;
correct response formation (HTTP-headers).

Problem

There are problems with cross-browser compatibility like displaying on different screen resolutions.

Solution

We check code correctness, its compliance with W3C standards and fix problems where needed (ex. write special code-snippets for correct web-page display in Internet Explorer).

Problem

Customers visit site, but target action (e.g. purchase) hasn’t happened, i.e. poor conversion rate on website.

Solution

Our programmers analyse the reasons behind such behaviour – such as a problem with interface complicity, an uncomfortable bar arrangement, etc. At the end, they implement a solution aimed at increasing your sales.

Problem

You want to optimize search and navigation bars to be more attractive and convenient for visitors.

Solution

Search box optimization is performed by:

keywords usage;
ads and partnership involvement.

And for navbar optimization we offer the following steps and their combination:

dropdowns usage;
search filters input;
search categories duplication;
application of autosuggest.

Problem

You have doubts regarding the security level on some pages and want to ensure users’ restricted access to some sections of website or cms for a reasonable cost.

Solution

For this problem solving we bring an expert with many years of successful experience in maintaining banking systems security. As it is well known that banking system requirements in the field of security are very strict, with no allowance for the slightest mistake, you can rest assured by the comprehensive security of needed data.

Problem

Your team needs understanding of errors in program code.

Solution

To solve this problem we can offer you our code-review service . After this procedure you’ll be sure your product works properly not only outside, but inside too.

Problem

Your website became unresponsive or very slow due to high attendance rate.

Solution

We perform load testing, which simulates multiple parallel queries to the server. During this testing, we define parameters such as the fastest and slowest request durations, transferred data amount, data exchange speed, etc.

According to the testing results we tune the server by:

rewriting the code;
changing the data-storage structure on the server;
server’s feature configuration.

All these steps will help to prevent website overload.

Problem

You have problems with interface perception by your users.

Solution

Usability Interface testing perfectly addresses this problem. It evaluates the following indicators:

efficiency - how many steps and how much time the user needs for the performance of the main tasks: goods placement, ordering, etc;
accuracy - how many errors were made by user while using the product;
recall - how much the user remembers after long-time suspension from product;
emotional response - how user feels about himself after working with the product - is he confused, stressed, or pleased? Will he recommend the system to friends?
