+
+The `grails-testing-support-mongodb` library provides support for testing GORM for MongoDB with Testcontainers. This library is suitable for both unit and integration testing.
+
+== Installation
+
+To use the MongoDB testing support, add the following dependency to your `build.gradle`:
+
+[source,groovy,subs="attributes"]
+testImplementation "org.apache.grails.testing:grails-testing-support-mongodb"
+
+== Usage
+
+You can use the `grails.test.mongodb.MongoSpec` trait to test MongoDB interactions. This trait will automatically start a MongoDB container using Testcontainers if one is not already running.
+
+[source,groovy]
+----
+import grails.test.mongodb.MongoSpec
+import spock.lang.Specification
+
+class MyMongoSpec extends Specification implements MongoSpec {
+
+    void "test mongo connection"() {
+        expect:
+        mongoClient != null
+    }
+}
+----
+
+The `MongoSpec` trait ensures that a MongoDB container is running and provides a `mongoClient` bean.
+
+== Advanced Configuration
+
+The testing support uses `AbstractMongoGrailsExtension` to manage the container. You can configure the MongoDB version using the `mongodbContainerVersion` system property, which defaults to `7.0.19`.
+
+Example of setting the version in `build.gradle`:
+
+[source,groovy]
+----
+tasks.withType(Test) {
+    systemProperty "mongodbContainerVersion", "7.0.25"
+}
+----
