Testing Ultimate-dependent plugins in 2025.3

IntelliJ Platform
1

I have a plugin I want to upgrade that depends on Ultimate features. Previously, my tests were working on 2025.1, now they fail on 2025.3:

I could resolve initial errors with the IDE home path by replacing an explicit test dependency with the testFramework helper:

Now I’m running into different issues that seem to be related to the unified distribution change:

internal class NoJQuerySelectorInspectionTest : BasePlatformTestCase() {

    @Test
    fun testJqAttributeHasWarning() {
        myFixture.enableInspections(NoJQuerySelectorInspection::class.java)
        myFixture.configureByText("test.jsp", """
            <script><warning descr="Do not use jQuery: ${'$'}('selector')">${'$'}('selector')</warning></script>
        """.trimIndent())

        myFixture.testHighlighting()
    }
}

Unregistered inspections requested: [com.example.intellij.codequality.inspection.javascript.NoJQuerySelectorInspection]

The inspections aren’t loaded automatically, likely because the plugin has a dependency on JSP (<depends>com.intellij.jsp</depends>). If I remove that dependency, the JavaScript inspection tests pass, the JSP inspection tests keep failing. If I add the dependency again, all of the inspection tests fail with an “Unregistered inspection” exception.

What’s the correct way to test Ultimate-dependent plugins in unit tests in 2025.3?

I finally fixed it by adding a dependency on com.intellij.javaee in the plugins.

platformBundledPlugins = com.intellij.javaee,com.intellij.jsp,JavaScript

dependencies {
    intellijPlatform {
        intellijIdea(properties("platformVersion")) {
            type = IntelliJPlatformType.IntellijIdeaUltimate
        }

        bundledPlugins(providers.gradleProperty("platformBundledPlugins").map { it.split(',') })
    }
}
