Business Intelligence and Data warehousing

With the pace of business change today, enterprises are challenged to keep up with and respond to changes in their business environment. Getting ahead of competition requires quick decisions. But more important than making a quick decision is making the right decision and tracking its business impact in near real-time. Using the right Business Intelligence and Data Warehousing solutions is essential in providing customers with critical business information needed to handle and overcome these increasing challenges.

The foundation of any Business Intelligence implementation is the Data Warehouse. Whether it supports the entire enterprise or just a departmental solution, Arriys’s Data Architects can help conceptualize, design and implement your Data Warehouse solution.

Test Automation

Products are getting complex and support costs have become higher. With the mounting quality demands and tight release cycles, testing has become a strain on the product development team and on budgets. This is where Arriys 's test automation services can help with the latest automation technologies and approaches to test automation.

Automated testing is not a silver bullet; but when rightly applied it can save costs, reduce cycle time, and increase accuracy. Arriys provides independent software testing services, which focus on an automated approach that leverages our innovative methodologies and experience.

The Arriys Approach:

Automation is widely misunderstood to be a simulation of user actions, achieved by simple record-and-play macros. However, the true value of automation lies in validating user actions, and therefore the focus of automation is on automating the validation algorithm.

Validation can be done in many ways:

By checking the state of the UI after the action.
By checking the returned data in the UI or by querying the database.
By comparing data from the test environment with data from a known environment.

To facilitate validation, Arriys builds automation frameworks (or test harnesses) that allow scripts to be plugged in, reused or re-designed with minimal effort. Arriys also focuses on integrating the test harness with the bug database and the test case database, so that test cases are updated and bugs are reported automatically.

Automation Process:

Automation Areas

Unit Testing:

Automating unit tests is a challenge, but in situations where it can be achieved, the effort pays off many times over. A typical method to automate unit testing is to use test applications/samples which automate APIs of a component with different combination of inputs and outputs.

Test Lab Setup: Setting up and configuring software and hardware for every build is a time-consuming activity. Automating this allows testing to start earlier, reducing cycle times.

Build Process:

Daily builds are desirable, but often unviable because of the time it takes to get the latest code from source control, label it, rebuild the binaries, and deploy the software for testing. This process sometimes takes half a day for complex software. Automating the build process makes daily builds a viable part of the process; it not only saves time and effort, but also ensures that developers can very quickly get information about the quality of their code.

Build Verification Test (BVT):

Iterations between Dev and Test teams can be reduced by automating BVT tests that allow the test team to quickly evaluate whether builds are of acceptable quality

Functional and Regression Testing:

Automating regression test suites ceases to be straightforward in the case of product modification where each build is designed to change the behavior of the software and the test output. Arriys adopts inventive approaches to effectively automate testing in such scenarios.

Performance/Stress/Reliability Testing:

These tests invariably need simulated conditions of load or stress on the system. The simulations are automated and repeated multiple times, each time varying different parameters, to detect bottlenecks.
