Introduction
This article presents unique tool to run repeatable performance tests in actually developed application by programmers.
The NTime tool is very similar to {NUnit} tool - an another unit testing tool, so currently users that use NUnit should see almost same GUI and functionality.
Background
This is the first release of tool to perform repeatable tasks that help managers, architects, developers and testers to test application against its performance.
This version may work inconsistent and report some errors in different situations that may exist while running this tool, however it was tested for many reasons.
Architecture
NTime architecture is similar to NUnit tool, therefore some implementations that were introduced in NUnit may be similar to its users. This section shows features found in NTime tool.
Simultaneous Compile and Test Time
NTime tool may still be running while there is currently compilation process of application which we want to test. After application has been built, NTime will reflect all changes, you just need to run tests and wait for performance test results whether they are accepted or rejected.
Test Timings
Actually NTime's timings are high frequency timers that will rely on different onboard chipset's architecture. This difference will generate more or less precision in tests. The one disadvantage while profiling tests is system processes and CPU load. Although you've closed heavy loaded applications there may be other bad thing you may meet -- NTime need some CPU and threads to perform complex tests and therefore you can indicate about 10 microseconds overhead, so if you want to test high frequency running functions then write inside of test code "for" loop statement i.e. 100 loops and then test the result as specified time multiplied by 100.
SDK Documentation
NTime tool is supported with two documentation files. The NTime Framework SDK will be your starting point to test your applications against performance tests by adding .NET attributes into your code.
NTime Framework SDK
NTime Framework SDK will be your often SDK documentation. This help file shows you available .NET attributes you can use in your testing applications. Many attributes are similar to NUnit attributs so when you've used NUnit tool before then starting to work with NTime will be easy.
NTime GUI SDK
After NTime installation you will find NTime source documentation. This will help you add some functionality to NTime for your own, but remember that every changes you've made to this tool are for your private and non-commercial use. Read License.rtf file for further information about NTime licensing.
Further Development
This NTime version is a GUI only application, next to do i have in future is to develop console application to provide batch script usability. For better NTime tool improvements, you may send comments to adamslosarski@tlen.pl with your suggestions to help me get application working better. Bugs found in this release will be fixed in next version, so earlier found errors will be corrected fast as possible. NTime sources will be available soon on the sourceforge.net website so you can track the next versions.
