WPF Global Exception Handler

Tuesday, December 9, 2014

I decide to write this post because I’m facing too many applications that crash, yes just crash – no massage or recovery just crash!!! For some application it feels like 50% chance to get an exception, for me when an application crashes frequently I stop using it when I can find a proper replacement, but not always I can find suitable a replacement. In case you don’t know what I’m talking about here is a small application I’ve created to demonstrate what I’m talking about. Now, it doesn’t required a lot of work to handle those unhandled...

How To: Enable Coded UI Html Logger

Monday, November 24, 2014

Many of my customers has already build large amount of Tests based on Coded UI, those tests running every build and every day, for a second everything looks just perfect, until a test failed with unexpected exception…. Then we need to understand why? the test failed because the new build broke the test? maybe something wrong with the test? So the obvious choice is adding logs to Coded UI, Coded UI has some basic logs capabilities, you can use either console, trace and TestContext to write logs inside your Coded UI Tests. Console.WriteLine("Console Writeline"); Trace.WriteLine("Trace Writeline"); TestContext.WriteLine("TestContext Writeline"); Now, if you...

Windows Azure Storage Emulator – v3.0 – Installation failed

Tuesday, July 1, 2014

Today I faced a very annoying and strange issue while installing newer version of Azure Storage Emulator on my machine. Tried to remove almost everything related to Azure but still nothing worked…. Although I ran DsInit to work on SQLEXPRESS instead of localdb I decide to delete sql local db by running the following commands: sqllocaldb stop v11.0 sqllocaldb delete v11.0 sqllocaldb create v11.0” The result should be - “LocalDB instance "v11.0" created with version 11.0.” After recreating SQL local db Azure Storage Emnulator worked. Hope this helped.

How To: Run Tests On Different Machines In Parallel

Wednesday, June 18, 2014

I’m getting this question a lot, how to run multiple tests on different machines in parallel? Every customer that I work with has over 100 tests and some has more than 1000+. So how to improve test execution time? running 1000+ tests can take a while and we want to get the results as fast as possible. So, for Unit Tests there is a nice trick (Wrote about it in 2010 –>Run Unit Tests in Parallel using Visual Studio 2010) that allow you to run those tests in parallel on the same machine. But what about Coded UI Tests? you most know we...

TFS API Part 51 – Adding Test Step & Shared Step

Monday, October 7, 2013

Working TFS API for Test Cases is different from Work Items, the usage is different and this cause many of customer to send me questions regarding Test Case API. This post will demonstrate how to create new Test Case, Adding Steps, Step Attachments, Shared Steps and more. As always we need to start with connecting TFS Object Model: TeamProjectPicker tpp = new TeamProjectPicker(TeamProjectPickerMode.SingleProject, false); if (tpp.ShowDialog() != System.Windows.Forms.DialogResult.OK) return; TfsTeamProjectCollection Tfs = tpp.SelectedTeamProjectCollection; For Work Items we need to obtain WorkItemStore object, but for Test Cases we need to work with ITestManagmentTeamProject object. ITestManagementServiceservice = (ITestManagementService)Tfs.GetService(typeof(ITestManagementService)); ITestManagementTeamProject TestProject = (ITestManagementTeamProject)service.GetTeamProject(tpp.SelectedProjects.Name); The ITestManagmentTeamProject contains many helpers for Test API TestPlans...

Could not load file or assembly ‘Microsoft.TeamFoundation.Client While Running Tests

Sunday, July 21, 2013

In my last post TFS 2012 Upgrade Process Template–Guide I’ve talked about upgrading an existing Team Project Template to another or a newer template.

So here is a simple tool to display the Base Process Template name. Download Demo Project Step 1: Connect TFS and Getting Team Projects Create WPF Application, and add the basic code for connecting...
