使用针对不同数据库的测试运行MSTest

I would like to ask what is the best way to execute a setup like the following: We have tests suite that is compiled, and in the app.config file I have 6-7 different connection strings to different databases. I would like to run the tests suite against every connection, and I hoped to parametrize in some way this process - something like setting the name of the connection and passing it on to the testrun as a parameter. What I figured out so far is that I can use different localconfigrun files and through deployment items I can feed a xml/txt file with the required value, but is there a nicer and lighter solution? I need just to send a key/value pair or simple string to configure my base class inside the test suite.I would like to ask what is the best way to exe
