Now all we have to do is to define one ore more environment variables in TeamCity for the build configuration of our project and the settings are picked upon the next execution: TeamCitiy Build Configuraiion Environment Variablesįor a complete example see IntegrationTestEnvironment.cs. $ENV:ABIQUO_API_BASE_URI or 'DefaultValue' In addition a conversion to the property type is also performed (as long as the target supports the implicit conversion or Convert.ChangeType()). To get started, we are going to need the following. Public string AbiquoApiBaseUri Īfter we have defined this class (which derives from .Commons available at NuGet) we only have to instantiate it and call Import() and all existing environment variables of the process are mapped to their properties. Note: This example assumes your build agent is running in a Linux-like environment. Some are passed in via the docker-compose, others are set in my agent Dockerfile when building the image, using RUN SETX /M NAME VALUE. Environment variables always override any settings in NuGet.Config files, allowing build servers to change appropriate settings without modifying any files.
Now we can create configuration classes like this where we defines the corresponding environment variable as an annotation with EnvironmentVariable (and also supply default values via the DefaultValue attribute if no corresponding environment variable is defined):īiz.dfch.CS. The agents are running in docker containers (windows server core), and I define various environment variables to be set on the agent containers, which ultimately get set as Windows env vars. The behavior of the nuget.exe CLI can be configured through a number of environment variables, which affect nuget.exe on computer-wide, user, or process levels. And while reading an environment variable in C is as easy as writing.
… it is still a nuisance to read and convert them into the correct data types – especially when we have a lot of these properties.Īs we are already making heavy use of our ConvertibleBaseDtoConverter (hmm – how does this name roll off the tongue ?) which supports annotation based conversion, we adapted this to support environment variables as well – enter EnvironmentVariableConverter: As we are using TeamCity as our build server (again thanks to JetBrains for our free open source license) we there can easily define evironment variables per build job to define environment specific settings that our tests can read so they can target the appropriate systems.
The problem is that we do not want to hard code any connection uris (or even worse credentials) into our unit and integration tests.Īs we are using TeamCity as our build server (again thanks to JetBrains for our free open source license) we there can easily define evironment variables per build job to define environment specific settings that our tests can read so they can target the appropriate systems.Īnd while reading an environment variable in C# is as easy as writing … The environment variable %env.DEV_S3_BUCKET% is already defined in Teamcity.When integrating back end systems we very often would like our build server to run integration tests against our test evironments. As TeamCity contains it's own, self-contained version of the Java Runtime (yes, TeamCity is a Java application), if you want to run any of the tools from the command line, you'll need to set up Environment Variables that match the install. What am I missing here? Is this possible to do this within a single step in Teamcity? Step 5: Configure Environment Variables for Java. Please note that the presence of any set environment variables will override those in a configuration file. I would have expected it to substitute the value for %env.DEV_S3_BUCKET% but it did not. The below bash script runs in Teamcity #!/bin/bash
