After cloning or downloading the sample you should be able to run it using an In Memory database immediately. The store's home page should look like this:. Most of the site's functionality works with just the web application running. However, the site's Admin page relies on Blazor WebAssembly running in the browser, and it must communicate with the server using the site's PublicApi web application. You'll need to also run this project. You can configure Visual Studio to start multiple projects, or just go to the PublicApi folder in a terminal window and run dotnet run from there.

After that from the Web folder you should run dotnet run --launch-profile Web. Note that if you use this approach, you'll need to stop the application manually in order to build the solution otherwise you'll get file locking errors. If you wish to use the sample with a persistent database, you will need to run its Entity Framework Core migrations before you will be able to run the app, and update the ConfigureServices method in Startup.

Update Startup. Ensure your connection strings in appsettings. Ensure the tool EF was already installed. You can find some help here.

These commands will create two separate databases, one for the store's catalog data and shopping cart information, and one for the app's user credentials and identity data. The first time you run the application, it will seed both databases with data such that you should see products in the store, and you should be able to log in using the demouser microsoft.

You can run the Web sample by running these commands from the root folder where the. You should be able to make requests to localhost for the Web project, and localhost for the Public API project once these commands complete.

If you have any problems, especially with login, try from a new guest or incognito browser instance. You can also run the applications by using the instructions located in their Dockerfile file in the root of each project. Again, run these commands from the root of the solution where the.

Scalability testing is used to determine if software is effectively handling increasing workloads. This can be determined by gradually adding to the user load or data volume while monitoring system performance.

Also, the workload may stay at the same level while resources such as CPUs and memory are changed. Volume testing determines how efficiently software performs with large projected amounts of data. It is also known as flood testing because the test floods the system with data. During performance testing of software, developers are looking for performance symptoms and issues. Speed issues — slow responses and long load times for example — often are observed and addressed.

O ther performance problems can be observed :. Image credit Gateway TestLabs. Also known as the test bed, a testing environment is where software, hardware, and networks are set up to execute performance tests. To use a testing environment for performance testing , developers can use these seven steps:. Identifying the hardware, software, network configurations and tools available allows the testing team to design the test and identify performance testing challenges early on.

Performance testing environment options include:. In addition to identifying metrics such as response time, throughput and constraints, identify what are the success criteria for performance testing. Identify performance test scenarios that take into account user variability, test data, and target metrics. This will create one or two models.

Analyze the data and share the findings. Run the performance tests again using the same parameters and different parameters. Metrics are needed to understand the quality and effectiveness of performance testing. Improvements cannot be made unless there are measurements.

Two definitions that need to be explained:. There are many ways to measure speed, scalability, and stability but each round of performance testing cannot be expected to use all of them. Among the metrics used in performance testing , the following often are used:. Also known as average latency, this tells developers how long it takes to receive the first byte after a request is sent.

This is the measurement of the longest amount of time it takes to fulfill a request. A peak response time that is significantly longer than average may indicate an anomaly that will create problems. This calculation is a percentage of requests resulting in errors compared to all requests. These errors usually occur when the load exceeds capacity.

This the most common measure of load — how many active users at any point. Also known as load size. Perhaps the most important tip for performance testing is testing early, test often. A single test will not tell developers all they need to know. Successful performance testing is a collection of repeated and smaller tests:.

Image credit Varun Kapaganty. In addition to repeated testing, performance testing will be more successful by following a series of performance testing best practices:.

Performance testing fallacies can lead to mistakes or failure to follow performance testing best practices.

According to Sofia Palamarchuk, these beliefs can cost significant money and resources when developing software :. As mentioned in the section on performance testing best practices, anticipating and solving performance issues should be an early part of software development.
