This simple library can help you test your XSL stylesheets against different XML document and assert the validity of transformations using XPath expressions.

You add this to your pom.xml:

<dependency>
  <groupId>org.eolang</groupId>
  <artifactId>xax</artifactId>
</dependency>

Then, creat this XSL file in src/main/resources/simple.xsl:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
  <xsl:template match="foo">
    <xsl:copy>
      <xsl:text>bye</xsl:text>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="node()|@*" mode="#default">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

Then, create this YAML file in src/test/resources/simple.yaml:

sheets:
  - simple.xsl
document:
  <doc><foo>hello</foo></doc>
asserts:
  - /doc/foo[.='bye']

Finally, make a unit test (using JUnit5, Hamcrest, and @ClasspathSource from Jucs):

import org.eolang.jucs.ClasspathSource;
import org.eolang.xax.XaxStory;
import org.hamcrest.MatcherAssert;
import org.hamcrest.Matchers;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.api.Test;

final class MyTest {
    @ParameterizedTest
    @ClasspathSource(value = "", glob = "**.yaml")
    void itWorks(String yaml) {
        MatcherAssert.assertThat(
            new XaxStory(yaml),
            Matchers.is(true)
        );
    }
}

Should work.
