 ## Spring Boot adapter tests
 
-Currently we are testing Spring Boot with three different containers `Tomcat 8`, `Undertow` and `Jetty [9.2, 9.3, 9.4]`. We are testing two versions of Spring Boot 1.5.x and 2.1.x. All versions are specified in [root pom.xml](../../pom.xml) (see properties `spring-boot15.version` and `spring-boot21.version`).

 ## Base UI tests
 Similarly to Admin Console tests, these tests are focused on UI, specifically on the parts of the server that are accessed by an end user (like Login page, or Account Console).
