Turn to functional testing in order to:

Immutability of stored records

  • No data alteration
  • No information tampering

No retroactive impact of smart contracts

  • No redeployment
  • No updates

How Reins solves blockchain testing challenges

Transaction irreversibility
Because of blockchain data immutability, no error can be reversed. So, we make sure that transaction details are correct before they are recorded on your blockchain.

Costly live testing
Performing blockchain tests in a live environment can be too expensive. We apply a testnet to cut down the associated QA costs.

Fee-based transactions
As any blockchain transaction comes with a fee, our task is to guarantee that all transaction- related processes in the network are error-free.

We ascertain that the software, be it web or mobile blockchain-based apps, is not vulnerable to attacks at the network, user and mining levels.

Multiple participants involved
With a limitless number of network participants operating from different geographical regions, we apply emulators of OSs and devices in use, as well as test on real devices.

Our blockchain testing services

Functional testing

We ensure that all the required functional ranges of essential blockchain product components are processed accurately, applying our creative approach to cover every possible user scenario.

Security testing

The Reins experts verify that the keys storage and encrypting system effectively ward off potential security attacks. We will also assess the robustness of authorization systems.

Performance testing

To ensure consistent quality, we will identify performance bottlenecks, assure that the app works smoothly under specific workloads and is ready for production.

Integration testing

Our experts test the cohesiveness and operability of intersystem connections across all blockchain app environments and integrated components.

Smart contract testing

Our QA professionals will simulate, review, and predict all possible conditions in the smart contract logic and conduct checks considering dynamically changing operational networks, code self-consistency, and invariant bricks.

Test automation

We implement test automation to save time, considering a large number of nodes, their combinations and validations during contract processing, as well as the rapid network growth and transformation.

We apply a tailored approach to blockchain testing
