### Tests on source code contents
|
|
|
|
Wat is de bedoeling? Lees alle source files in en check of er iets in voorkomt (in onderstaand geval `Bla.Instance`)
|
|
|
|
De `GoUpThreeDirs` is omdat bij unit testen draaien dit in rootDir/unitTestProject/Bin/Debug uitgevoerd wordt, dat is de huidige dir. wij hebben nodig: rootDir/sourceCodeProject.
|
|
|
|
```csharp
|
|
[TestMethod]
|
|
public void StaticInstanceShouldNeverBeUsedExceptInAllowedCases()
|
|
{
|
|
foreach (var file in Directory.GetFiles(GetSourcePath(), "*.cs", SearchOption.AllDirectories))
|
|
{
|
|
var source = File.ReadAllText(file);
|
|
if (source.Contains(typeof(Bla).Name + ".Instance") && NoStaticRefAllowedInThatFile(file))
|
|
{
|
|
Assert.Fail("file " + file + " contains a static reference to Bla which is not allowed!" +
|
|
"Please use Dependency Injection instead, take a look at the existing repositories as an example.");
|
|
}
|
|
}
|
|
}
|
|
|
|
private bool NoStaticRefAllowedInThatFile(string file)
|
|
{
|
|
List<Type> allowedTypesWithInstanceRef = new List<Type>()
|
|
{
|
|
typeof(Bla),
|
|
typeof(Blie)
|
|
};
|
|
|
|
return allowedTypesWithInstanceRef.All(x => !file.Contains(x.Name));
|
|
}
|
|
|

private static string GetSourcePath()
|
|
{
|
|
return GoUpThreeDirectories(Environment.CurrentDirectory) + "<br/><br/>ProjectNameOfSourceCode";
|

}
|

|
|
private static string GoUpThreeDirectories(string dir)
|
|
{
|
|
string rootDir = dir;
|
|
for (var i ###### 1; i < 3; i++)
|
|
{
|
|
rootDir = rootDir.Substring(0, rootDir.LastIndexOf("<br/><br/>", StringComparison.Ordinal));
|

}
