java - Maven failure on spring boot test (junit 5) -


is possible run spring boot tests junit 5 using maven? i'm using spring boot 2.0.0.m3, junit 5.0.0-m6, maven 3.5.0. other junit5 tests (without spring context) works.

there simple controller:

@controller public class homecontroller {     @getmapping("/")     string home() {         return "home";     } }

and test:

@extendwith(springextension.class) @webmvctest(homecontroller.class) @import(securityconfig.class) class homecontrollertest {      @autowired     private mockmvc mvc;      @test     void shouldreturnhometemplate() throws exception {         this.mvc.perform(get("/").accept(mediatype.text_html))             .andexpect(status().isok())             .andexpect(content().string(startswith("<!doctype html>")));     } }

everything works when run using intellij, maven build ends failure:

inside 2017-07-28t13-50-15_071-jvmrun1.dumpstream can find ~100 same exceptions (one per spring log):

intellij bundles junit5 intellij , maven using different versions.

see junit5 docs intellij

depending on version of intellij running, executing earlier junit5 milestone release maven using.

if you're on 2017.2, try switching junit5 dependency in pom.xml m4 , see if solves incompatibility.

also try specifying junit-jupiter-engine:5.0.0-m4 in plugin dependency in pom.xml junit-platform-surefire-plugin.

i using 5.0.0-m5 way.

[update 2017-08-10]: regarding comments, using spring boot 1.5.4.release can't like-for-like comparison.

you don't version of intellij using - assuming tests still working under intellij, version configuration target, presumably. in maven projects view or debug test output classpath , see versions in use.

spring managing lot of versions you. using spring-boot parent pom, or depending on spring-boot-starter dependencies?

to find out going on , spring dependency pulling in junit5 dependency breaking, run

mvn dependency:tree

and go through list of dependencies , versions see have under maven.

you may find versions think have specified being overridden, , have put exclusions in pom stop that.

[update 2]: quick change - try putting junit-jupiter-engine dependency in maven-surefire-plugin dependency block next junit-platform-surefire-provider:

        <plugin>             <groupid>org.apache.maven.plugins</groupid>             <artifactid>maven-surefire-plugin</artifactid>             <version>2.19.1</version>             <dependencies>                 <dependency>                     <groupid>org.junit.platform</groupid>                     <artifactid>junit-platform-surefire-provider                     </artifactid>                     <version>1.0.0-m5</version>                 </dependency>                 <dependency>                     <groupid>org.junit.jupiter</groupid>                     <artifactid>junit-jupiter-engine</artifactid>                     <version>5.0.0-m5</version>                 </dependency>             </dependencies>         </plugin>

note i'm not yet on version 2.20 (and i'm still on 5.0.0-m5) - sorry don't have time try week either.

you see if setting maven-surefire-plugin config forkcount=0 see if gives better exception message.

you strip down project bare minimum , open jira issues maven , spring testing. changed tags on question incluide spring-boot 1 of guys might take notice. or might not, depending on luck - find more react if tweet stackoverflow url @springboot.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
