Quality Assurance & Testing

Develop bug-free, high-performance and masterfully executed software applications thanks to manual and automated testing.

Why is software testing important for your business?

Cost savings

Experienced testers are familiar with the project’s risks early on, which helps you make better-informed business decisions. As late-found bugs or issues in a product can come at great financial costs, QA saves you time, money and reasons to worry.

End-users perspective

Testers know how to empathise with your target audience and see your application through their eyes. They play out different roles depending on who’s your go-to customer: a child, an adult, or an elderly person. By using special methods and proven testing tools, it's easier to accomplish a quality product!

Bug-free application

The product undergoes a rigorous analysis before it gets out into the world. We make sure it is as error-free as possible and that every component works perfectly. However, some issues may appear after the release, so we recommend ongoing QA support.

Ongoing support

We recommend that a QA is present in each team and at every stage of the software development process. In the testing phase, we verify the accuracy of our solutions, identify errors, make necessary bug fixes, and then we double-check the final outcome.

Improves user experience

One of the main reasons why users uninstall an app or give up on browsing a website is frustration caused by bugs. Five-star rated products are continuously improving user experience, and that's why QA is of utmost importance in the growth phase of your product.

Importance of high-quality

Just like any successful product on the market, your software needs to meet the highest standards and live up to your target audience's expectations. Testing is a common practice to maintain the correctness of source code as well as guaranteeing a seamless customer experience. 

100% accurate

… to initial assumptions. We know that the digital solution has to match perfectly with your business requirements.  QA is your greatest ally and makes sure the project is satisfactory from your perspective.

Manage severe risks

It’s important to identify and correct vulnerabilities before they could lead to any unwanted consequences. Prevent system failures, workload slowdowns, data breaches, or various security issues with the help of a reliable QA provider.

Business Analysis

It's important for Quality Assurance (QA) to understand the purpose and desired outcome of each feature at the beginning of a project. Business analysts typically translate the client's needs into technical language and create user stories, available from now on from the product’s backlog.

Successful development of a mobile e-signature solution

Scrive, a premium eSign enterprise based in Stockholm, reached out to hero/dot after an unsuccessful partnership with another software company. We upgraded Scrive's existing iOS application and delivered an Android application, taking full responsibility for the development of the product.

After 3 years of maintaining the apps, we also rebuilt them in Flutter. The result of the project is reflected in Scrive's market position, with over 6000+ customers in over 50+ countries and more than a million transactions processed per month.

QA & Testing Glossary

Here are a few useful definitions that may come handy once you start collaborating with us!

User Stories
In agile methodologies, such as Scrum, user stories are prepared by a business analyst or product owner. They describe a functionality from the end-user perspective and their acceptance criteria. The typical formula of a user story goes like that: as a [user], I want [functionality], so that [benefit].
Test scenario
Testers use test scenarios to outline how a single feature or a combination of features should work. These are easily evaluable in accordance with how a real-life user thinks and acts. Let’s look at an everyday activity, like logging into your email account, to see how the test scenario is broken into multiple test cases.
Test case
In this test scenario – you are logging into your email – if you use an incorrect username and password, you are forbidden to enter. The same happens when only the username or password is incorrect. However, if your username and password are correct, you easily log in. These are the four test cases in a described scenario.
Test plan
This higher-lever document includes the scope, objectives, type of tests (manual or automated), date and hour, as well as the type of browser we tested the application on (mobile or web). The test plan is our point of reference for double-checking the whole application at the end of each round.
