NLog with Visual Studio Unit Test
| We all have been writing unit tests for quite some time. We all have also used NLog for logging DEBUG's, ERRORS and TRACES in our web application and web services. But after searching for a long time to implement NLog in visual studio unit test framework, I got no success. My test results we still getting logged in test results.trx files containing huge amount of data. In this post I am going to show you how we can use NLog to log our messages in log files same as we do in web applications and web services. For enabling logging in our unit test framework, open the app.config and include the following references: |
1: <configuration>
2:
3: <configSections>
4: <section name="nlog"
type="NLog.Config.ConfigSectionHandler, NLog"/>
5: </configSections>
6:
7: <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
8: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
9:
10: <targets>
11: <target name="file"
12: xsi:type="File"
13: layout="${longdate} ${level:uppercase=true} ${message}"
14: fileName="C:/logs/${machinename}-applog.log"
15: archiveEvery="Day"
16: archiveFileName="C:/logs/applog.{#####}.log"
17: archiveNumbering="Sequence"
18: keepFileOpen="true"
19: encoding="iso-8859-2"
20: maxArchiveFiles="32"
21: />
22: </targets>
23: <rule>
24: <logger name="*" minlevel="Trace" writeTo="file"/>
25: </rule>
26:
27: </nlog>
28:
29: </configuration>
Now in the ClassInitize event, add the following code to initialize the logger:
1: NLog.Logger logger = LogManager.GetLogger("UnitTestLogger");
2: logger.Trace("Logger Created");
Here you go. Follow the path C:\Logs to view messages getting logged.
Happy Programming!!!
