########## File path: scala-package/packageTest/README.md ########## @@ -0,0 +1,72 @@ +# MXNet Scala Package Test + +This is an project created to run the test suite on a fully packaged mxnet jar. The test suite is found locally but mxnet is from the target jarfile. + +## General Setup + +To setup the packageTest, you must first build your tests. To build the tests, follow these steps from the mxnet main directory: + +1. Build MXNet and the scala package from source following the directions [here](https://mxnet.incubator.apache.org/install/scala_setup.html#source) +2. Build the tests by running `make scalatestcompile`. +3. Follow setup instructions below for your testing goal + +## Running + +There are three different modes of operation for testing based on the location of the jar and where it is coming from: + +### Test Installed Jars + +If you have a jar file, you can install it to your maven cache repository(`~/.m2/repository`). This might be useful if you acquire the .jar file from elsewhere. To install, it is easiest to use `mvn install:install-file -Dfile=<path-to-file> -DpomFile=<path-to-pomfile>`. If the pom file is not available, you can also run `mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>`. With the full mxnet jar, this might look like `mvn install:install-file -Dfile=<path-to-file> -DgroupId=org.apache.mxnet -DartifactId=mxnet-full_2.11-linux-x86_64-cpu -Dversion=1.3.0 -Dpackaging=jar`. + +You can also run `make scalainstall` to install from a local build. + +After installing, run `make testinstall` in the package test directory to run the tests. Note that unless you also install an additional mxnetexamples jar, you can only run the unit tests. + +### Test Local Deployment + +To test the jars that would be produced by a deployment, you can run `make scaladeploylocal` from the main mxnet directory. This produces a local snapshot located at `scala-package/local-snapshot`. To test this local snapshot, run `make testlocal`. + +### Remote Repository Snapshot + +This mode is to test a jar located in a remote repository. The default repository is the apache snapshot repisotory located at `https://repository.apache.org/content/repositories/snapshots`. Note that the actual jar in a repisotory should be located at `$repoUrl/org/apache/mxnet/mxnet-full_$scalaVersion-$osMode/$version/*.jar`. + +Test the snapshot repo using `make testsnapshot` or a different repo using `make testsnapshot MXNET_REPO=$NEW_REPO_URL`. + +### Options + +You are able to run unit tests, integration tests, or both using this utility. To run the unit tests, add the flag `UNIT=1` to make (e.g. `make testsnapshot UNIT=1`). Use `INTEGRATION=1` for integration tests. The default behavior is to run both the unit and integration tests. However, the integration tests require that the mxnet examples be installed in addition to the full mxnet package (see test mode instructions above). + +An additional option, you can specify the mxnet version with `MXNET_VERSION=1.3.1-SNAPSHOT`. + +## Cleaning Up + +You can clean temporary files and target artifacts by running `make scalaclean`. + +## Troubleshooting + +### Missing Examples + +If you fail with the following error +``` +[ERROR] Failed to execute goal org.scalatest:scalatest-maven-plugin:1.0:test (test) on project mxnet-scala-packagetest-examples_2.11: There are test failures -> [Help 1] +[ERROR] +[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. +[ERROR] Re-run Maven using the -X switch to enable full debug logging. +[ERROR] +[ERROR] For more information about the errors and possible solutions, please read the following articles: +[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException +[ERROR] +[ERROR] After correcting the problems, you can resume the build with the command +[ERROR] mvn <goals> -rf :mxnet-scala-packagetest-examples_2.11 +Makefile:57: recipe for target 'scalaintegrationtest' failed +make: *** [scalaintegrationtest] Error 1 +``` + +and stacktrace begins with the following, + +``` +*** RUN ABORTED *** + java.lang.NoClassDefFoundError: org/apache/mxnetexamples/Util$ +``` + +you are missing the mxnetexamples package.
