Adding Resolution Paths during appdomain creation (Compatibility Isuue) #404

jayaranigarg · 2018-04-19T10:24:04Z

Scenario which was broken -
If suppose TestProject has a config file having assembly binding redirect of System.Runtime to 4.1. Our TestAdapter which has a dependency of System.Runtime of 4.0, uses the above config file and tries to load System.Runtime 4.1. Since assembly resolver was not set at the time of loading of adapter, it is unable to find 4.1 version of assembly and bombs.

Fix - Adding resolution paths at the time of creation of appdomains.

Validations-

2 Projects having different adapter versions works fine with enable and Appdomain
Above scenario.

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

        public void SetupHost()
        {
-            if (this.AppDomainCreationDisabledInRunSettings())
+            List<string> resolutionPaths = this.GetResolutionPaths(this.sourceFileName, VSInstallationUtilities.IsCurrentProcessRunningInPortableMode());


Please add test for ResolutionPaths being set.

+                }

-            this.targetFrameworkVersion = this.GetTargetFrameworkVersionString(this.sourceFileName);
+                // Adding extensions folder to resolution paths


Nit: this is runner location(OM assembly location).

smadala · 2018-04-19T11:00:45Z

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+            List<string> resolutionPaths = this.GetResolutionPaths(this.sourceFileName, VSInstallationUtilities.IsCurrentProcessRunningInPortableMode());
+
+            // Check if user specified any runsettings
+            MSTestAdapterSettings adapterSettings = MSTestSettingsProvider.Settings;


Move the declaration near to usage.

smadala · 2018-04-19T11:05:36Z

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+            // Check if user specified any runsettings
+            MSTestAdapterSettings adapterSettings = MSTestSettingsProvider.Settings;
+
+            if (resolutionPaths != null && resolutionPaths.Count > 0)


This should not be happen. Even if it is empty or null, We should add below two paths.

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+                    }
+                    catch (Exception exception)
+                    {
+                        if (EqtTrace.IsErrorEnabled)


Nit: Remove if check for error scenarios.

+                    {
+                        if (EqtTrace.IsErrorEnabled)
+                        {
+                            EqtTrace.Error(exception);


Nit: Add more details while logging the exception. At line 190 too.

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+                var configFile = this.GetConfigFileForTestSource(this.sourceFileName);
+                AppDomainUtilities.SetConfigurationFile(appDomainSetup, configFile);
+
+                this.domain = this.appDomain.CreateDomain("TestSourceHost: Enumering assembly", null, appDomainSetup);


Change the name of appdomain to sourcefilename.

smadala · 2018-04-19T12:56:05Z

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

-
-            // Case when Child-appdomain was created successfully, update appbase and set assembly resolver on it
-            else if (this.domain != null)
+            if (this.domain != null)


Change this to inverted if IsAppDomainCreationDisable.

smadala · 2018-04-19T12:56:42Z

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs


            // Log error when child-appdomain was expected to be created but wasn't created.
-            else
+            else if (!this.AppDomainCreationDisabledInRunSettings())


This is not required. Are DisableAppDomain settings from runsettings only once.

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+                    try
+                    {
+                        var additionalSearchDirectories =
+                            adapterSettings.GetDirectoryListWithRecursiveProperty(this.domain.SetupInformation.ApplicationBase);


this.domain.SetupInformation.ApplicationBase value should be testsource directory.

Reuse additionalSearchDirectories.

smadala · 2018-04-19T13:18:01Z

src/Adapter/PlatformServices.Desktop/Services/DesktopTestSourceHost.cs

+                    try
+                    {
+                        this.parentDomainAssemblyResolver = new AssemblyResolver(resolutionPaths);
+                        this.parentDomainAssemblyResolver.AddSearchDirectoriesFromRunSetting(adapterSettings.GetDirectoryListWithRecursiveProperty(null));


GetDirectoryListWithRecursiveProperty should take test source directory.

Make it internal.

Remove this if not required?

Required. SampleFrameworkExtensions also has it. PlatformServices.Desktop.Component.Tests throws strong name error if key.snk is not referenced in TestProjectForAssemblyResolution.
