Running JUnit-Tests that uses SWT-Display fails on Jenkins - swt

I a have a few JUnit-Tests that makes use of the current Display to instantiate a few controls (TreeViewer for instance). Locally that works fine, no problem. When I commit these tests and jenkins runs the test I get a failed test for each test that makes use of Display.
My unit test uses the display variable in this manner:
#Test
public void testUtils() {
Display display = Display.getCurrent();
Shell shell = new Shell(display, SWT.NONE);
// org.eclipse.swt.widgets.Composite composite = new
// org.eclipse.swt.widgets.Composite(
// shell, SWT.NONE);
TreeViewer viewer = new TreeViewer(shell, SWT.MULTI | SWT.H_SCROLL
| SWT.V_SCROLL);
The error log jenkins generates is:
Time elapsed: 0.13 sec <<< ERROR!
org.eclipse.swt.SWTError: No more handles [gtk_init_check() failed]
at org.eclipse.swt.SWT.error(SWT.java:4109)

Is there any thing wrong with the way I am using Display in my tests? It works when executed on my local machine

The way you use Display looks OK to me. The error is likely related to the fact that your server is not running Gnome, hence SWT can't create a Display when you ask it to.
UPDATE
I just found a recent blog post, which explains what you need to do to run SWT UI tests on a headless server in more detail. Although the steps provided are meant for Hudson, they should be applicable to Jenkins as well.
It should all boil down to these two steps:
Check Run Xvnc during build (and don’t bother to check take screenshot, it doesn’t work)
Add an Execute shell build action before launching your tests with metacity –replace –sm-disable &
See the linked blog post for screenshots and more details.

You can try following two things,
execute command "xhost" or "xhost+" from your terminnal.
execute command "xhost" or "xhost+" from, jenkins terminal.

Karate- Gatling: Not able to run scenarios based on tags

I am trying to run performance test on scenario tagged as perf from the below feature file-
#tag1 #tag2 #tag3
**background:**
user login
#tag4 #perf
**scenario1:**
#tag4
**scenario2:**
Below is my .scala file setup-
class PerfTest extends Simulation {
val protocol = karateProtocol()
val getTags = scenario("Name goes here").exec(karateFeature("classpath:filepath"))
setUp(
getTags.inject(
atOnceUsers(1)
).protocols(protocol)
)
I have tried passing the tags from command line and as well as passing the tag as argument in exec method in scala setup.
Terminal command-
mvn clean test-compile gatling:test "-Dkarate.env={env}" "-Dkarate.options= --tags #perf"
.scala update:- I have also tried passing the tag as an argument in the karate execute.
val getTags = scenario("Name goes here").exec(karateFeature("classpath:filepath", "#perf"))
Both scenarios are being executed with either approach. Any pointers how i can force only the test with tag perf to run?
I wanted to share the finding here. I realized it is working fine when i am passing the tag info in .scala file.
My scenario with perf tag was a combination of GET and POST call as i needed some data from GET call to pass in POST call. That's why i was seeing both calls when running performance test.
I did not find any reference in karate gatling documentation for passing tags in terminal execution command. So i am assuming that might not be a valid case.

Nunit won't discover working non explicit tests Visual studio 2022

I have 3 normal and 1 explicit test but when I run my test using the Test Explorer window I get this output under "Tests" in the Output window
========== Starting test run ==========
NUnit Adapter 4.2.0.0: Test execution started
Running all tests in xyz.dll
NUnit3TestExecutor discovered 1 of 1 NUnit test cases using Current Discovery mode, Explicit run
ExplicitMethod(03/10/2022 08:00:00,03/10/2022 16:00:00): OneTimeSetUp:
NUnit Adapter 4.2.0.0: Test execution complete
========== Test run finished: 1 Tests (0 Passed, 0 Failed, 0 Skipped) run in 462 ms ==========
*Note I'm using NUnit Adapter 4.2.1 instead of 4.2.0 so that's already weird
And this is how the Test Explorer window looks
Test Explorer window
*Note the full blue test is the Explicit test that get's skipped like it should
This is a problem because it does seem to only discover tests which are explicit.
The tests I want to run are of course not explicit, here is an example
[Test]
[TestCaseSource(nameof(TestNameData))]
public async Task<float> TestName(DateTime start, DateTime end, List<CalculateHoursObj>? list = default)
{
if (list == null) list = new List<CalculateHoursObj>();
return await EmployeeService.CalculateOverTimeHours(start, end, list);
}
public static IEnumerable TestNameData
{
get
{
yield return new TestCaseData(TenthMarch8_2022, TenthMarch16_2022).Returns(8.0f);
}
}
It fails to discover and/or run this test.
But curiously if I break all my non explicit tests by making the data non-static like this
public IEnumerable TestNameData
{
get
{
yield return new TestCaseData(TenthMarch8_2022, TenthMarch16_2022).Returns(8.0f);
}
}
It of course breaks the test and when I run all tests it does actually discover all tests
========== Starting test run ==========
NUnit Adapter 4.2.0.0: Test execution started
Running selected tests in xyz.dll
NUnit3TestExecutor discovered 2 of 4 NUnit test cases using Current Discovery mode, Non-Explicit run
NUnit Adapter 4.2.0.0: Test execution complete
========== Test run finished: 2 Tests (0 Passed, 2 Failed, 0 Skipped) run in 394 ms ==========
But even now it only runs 2 of the 3 broken non explicit tests and of course they all fail
I have looked up everything online for 1.5 hours and really can't find a solution.
Don't bother responding with "have you updated visual studio or the nugget packages"
This question was part of a bug the solution is to not use new DateTime() withing nunit tests or to have nunit test be discover with id's using the <UseParentFQNForParametrizedTests>true</UseParentFQNForParametrizedTests> <UseNUnitIdforTestCaseId>true</UseNUnitIdforTestCaseId> flags
This was a bug because it was not reported correctly in the output window and/or Error List window.
I've created an Issue on GitHub about this if anyone wants to read.
Now stop editing this post because it truly is answered and the Issue link which I included shows the valid, correct and readable answer by "OsirisTerje" whom explains it way better than I could.

VSCode extension testing: Use `vscode.executeDefinitionProvider` in test

Background
I'm trying to auto-test my VSCode extension. The extension works with python files and uses vscode.executeDefinitionProvider and vscode.executeDocumentSymbolProvider on them.
Problem
vscode.executeDefinitionProvider always returns [], vscode.executeDocumentSymbolProvider always returns undefined.
Notes
When running the same code in a debug session of the extension (no test session), the commands work flawless.
I ensured the extensions to be available during the test and even manually activated them with
let ext = vscode.extensions.getExtension("ms-python.python");
assert.notStrictEqual (ext, undefined);
await ext?.activate ();
ext = vscode.extensions.getExtension("ms-python.vscode-pylance");
assert.notStrictEqual (ext, undefined);
await ext?.activate ();
Question
How do I get the commands to succeed during automated test.
Edit: Workaround
Apparently VSCode takes its time to really activate the extensions. I could get it working placing a await sleep (10000); in index.ts::run () before return new Promise((c, e) => {.
While this is working, it's a really unstable workaround, Is there any way to make the code wait until the whole environment is fully loaded?
In the end nothing really stably worked for me, so I resorted to the following (perfectly fine working) solution.
My auto tests are run from the productive environment, like any other extension.
In package.json I created a new command _test.
the command would run ./test/suite/index.ts : run().
Extension<T>::activate(): Thenable<T>
Returns: Thenable<T> - A promise that will resolve when this extension has been activated.
await ext?.activate();

How to get Resharpers InspectCode to recognize Plugins?

I am trying to run ReSharpers command line tool InspectCode.exe. It's running fine doing it's job with the expected output.
However after my earlier attempt to get plugins to work, this time with the new version it is supposed to be supported. There is a switch in the command line interface that allows to specify the extension you want to use.
/extensions (/x) – allows using ReSharper extensions that affect code analysis. To use an extension, specify its ID, which you can find by opening the extension package page in the ReSharper Gallery, and then the Package Statistics page. Multiple values are separated with the semicolon.
But I cannot get it to work properly. I cannot even provoke any reaction to the /x switch at all. No matter how or what I pass, I get no feedback from the executable and the output is identical. I don't even get an error message when passing obvious garbage.
I tried the following commandlines for the exact same result:
inspectcode.exe /o="rcli.xml" /swea /x="ReSharper.StyleCop" "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ReSharper.StyleCop "my.sln"
inspectcode.exe /o="rcli.xml" /swea "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ABCDEFG "my.sln"

Running in 64-bit mode, .NET runtime 4.0.30319.18444 under Microsoft Windows NT

What am I doing wrong? How to get extensions to work?
I already tried the R# forums, but it took them more then 24h to approve my post and so far I'm not sure someone else even read it.
Unfortunately, the support for extensions was dropped in 9.0 due to the refactorings in the "ReSharper platform". I hope that JetBrains will bring it back soon.
See RSRP-436208.
This is a late answer that might help future readers (like myself). Currently inspectcode.exe will automatically look for and use any NuGet packages that are in the same folder as the executable (source).
Example for CleanCode extension:
if you have a R# instance on some machine and install the extension, it will be placed in C:\Users\{user}\AppData\Local\JetBrains\plugins\MO.CleanCode.5.6.15
copy MO.CleanCode.5.6.15.nupkg and paste it next to inspectcode.exe
when running inspectcode with verbosity = VERBOSE, the extension should appear in the Zones list:
$cmd = "..\JetBrains.ReSharper.CommandLineTools.2019.3.4\inspectcode.exe"
$outputFile = "..\Output\$($outputName).xml"
& $cmd -o="$outputFile" $sln --verbosity=VERBOSE

Why did SQL Server Management Studio 2008 command-line switches stop working?

I've always relied heavily on Windows shortcuts to SSMS that include command-line switches allowing me to quickly open up a specific database on a specific server. For example
Ssms.exe -S 123.123.123.123 -U sa -P goodpassword -d DbName
or
Ssms.exe -S . -E -d DbName
These suddenly stopped working. I get this error from SSMS:
Failed to create new SQL Server script.
Object reference not set to an instance of an object. (AppIDPackage)
Program Location: at Microsoft.SqlServer.Management.UI.VSIntegration.
AppIDPackage.AppIDPackage.OpenConnectionDialogWithGlobalConnectionInfo()
I can still launch SSMS without the command-line switches, and then manually establish the connections. Some command-line switches still work, for example
ssms.exe -nosplash
works fine.
I get the same error with any combination of the -S, -E, and -d command-line switches. It doesn't matter if I'm pointing to a valid server or database or not, or if my login credentials are good or not. I can point to the older version of SSMS and it works fine, but not the 2008 version.
This post on MSDN's forums is all I've found online, but MS hasn't been very helpful on this thread.
Any ideas how I might start to fix this? I work with a lot of different databases on different servers, and I really rely on these shortcuts.
I've thrown the DLL in question at reflector and it's given me back the code at the bottom of this post, sadly there's nothing immediately obvious in the code that makes it easy to work out why it's stopped working for you (wouldn't it be nice if Microsoft shipped debug symbols with anything they produce that's written against the CLR?).
There are a couple of places where the code makes me wonder if you might have a corrupted "recently used servers" list or something similar, perhaps you could try following the steps listed in this question to clear them out and see if that helps.
private void OpenConnectionDialogWithGlobalConnectionInfo()
{
if ((ServiceCache.GlobalConnectionInfo != null) && (ServiceCache.GlobalConnectionInfo.Count != 0))
{
try
{
using (ConnectionDialog dialog = new ShellConnectionDialog())
{
IDbConnection connection;
dialog.ImportRegisteredServersOnFirstLaunch = true;
dialog.AddServer(new SqlServerType());
UIConnectionInfo connectInfo = ServiceCache.GlobalConnectionInfo[0].Copy();
if (dialog.TryToConnect(this.PopupOwner, ref connectInfo, out connection) == DialogResult.OK)
{
this.ScriptFactory.CreateNewBlankScript(ScriptType.Sql, connectInfo, connection);
}
}
}
catch (Exception exception)
{
ExceptionMessageBox box = new ExceptionMessageBox(new ApplicationException(SRError.FailedToCreateNewSqlScript, exception));
box.Caption = SRError.MessageBoxCaption;
box.Show(this.PopupOwner);
}
}
ServiceCache.GlobalConnectionInfo = null;
}
The ObjectExplorer window must be open. Don't hide.
I solved my problem this way :)
Works fine like this:
sqlwb.exe -S . -E -d dbName
I'm using SSMS2008 against a SQL2005 database, and the ssms command line works fine here.
This is the version info produced by the SSMS About dialog:
Microsoft SQL Server Management Studio 10.0.1600.22 ((SQL_PreRelease).080709-1414 )
Microsoft Data Access Components (MDAC) 6.0.6001.18000 (longhorn_rtm.080118-1840)
Microsoft MSXML 2.6 3.0 5.0 6.0
Microsoft Internet Explorer 8.0.6001.18813
Microsoft .NET Framework 2.0.50727.3074
Operating System 6.0.6001
There are several sources (MSSqlTips, and here) that state the command line arguments are available on sqlwb.exe. Yet the Books Online page for ssms states that the options are available on ssms.
