Enhancing reliability in Microsoft Fabric and Azure Synapse through load testing

Microsoft has employed Azure Load Testing to enhance the reliability of Microsoft Fabric and Azure Synapse, ensuring they can handle high loads. Azure Synapse integrates various data analytics technologies, while Microsoft Fabric offers a full enterprise analytics solution. Through rigorous daily and weekly load testing, involving complex scenarios and extensive data sizes, Microsoft aims to identify and rectify potential issues, ensuring optimal performance. This testing, integrated within their development pipelines, supports continuous improvement, leverages Azure's scalability, and utilizes Power BI for detailed reporting, ultimately enhancing service reliability and user experience.


Testing the MSVC Compiler Backend

This post provides a behind-the-scenes look at how we test MSVC's backend, which is responsible for optimization and code generation. Many people worldwide use our compiler and expect it to provide a high-quality experience in terms of correctness (compiled code behaves as written), performance (speed of the compiled code), and throughput (...


IntelliTest simplifies writing and maintaining unit tests

Writing a suite of unit tests that exhaustively exercise and validate the logic of the code is not easy. It can even be considered too expensive to do at all. Fortunately, IntelliTest addresses both concerns: it helps you achieve high code coverage at a fraction of the cost, and now in Preview, this Enterprise feature supports projects that ...

Load testing your applications using Azure Load Testing, JMeter and GitHub Actions

Dominique St-Amand shares an introduction on JMeter concepts and goes on to create a basic test plan to load test a sample application and run it through a GitHub Action workflow. I’ve been working with more customers that are starting to take testing (unit, integration, end to end and load testing) more seriously. You may ask, “Dom...


An Approach to Unit Testing ADX Functions

Overview Our application contains many functions that return data stored in Azure Data Explorer (ADX). We wrote these functions in Kusto Query Language (KQL) and each function returns a set of data based on the arguments passed. Although developers tested these functions as they wrote them, we needed a way to validate that the functions ...
