This directory contains jtreg tests which are wrapper tests to execute Graal unit tests similar way they are run in Graal project.
|
|
|
|
|
The tests use compiler.graalunit.common.GraalUnitTestLauncher helper class to run Graal unit tests where the set of tests to execute
|
|
|
|
|
is specified by '-prefix' argument. GraalUnitTestLauncher launches ported com.oracle.mxtool.junit.MxJUnitWrapper to run Graal unit
|
|
|
|
|
tests as it is done by "mx unittest" command from Graal project.
|
|
|
|
|
|
|
|
|
|
All compiler/graalunit/*.java tests were automatically generated by generateTests.sh script which reads
|
|
|
|
|
"testName -> testPrefix [requiresStatement]" mapping from TestPackages.txt file and generates corresponding <testName>Test.java
|
|
|
|
|
tests. The mapping takes into account tests execution time to avoid very long test runs.
|
|
|
|
|
|
|
|
|
|
Graal unit tests depends on following external jar files:
|
|
|
|
|
asm-5.0.4.jar:
|
|
|
|
|
https://lafo.ssw.uni-linz.ac.at/pub/graal-external-deps/asm-5.0.4.jar
|
|
|
|
|
|
|
|
|
|
asm-tree-5.0.4.jar:
|
|
|
|
|
https://lafo.ssw.uni-linz.ac.at/pub/graal-external-deps/asm-tree-5.0.4.jar
|
|
|
|
|
|
|
|
|
|
junit-4.12.jar:
|
|
|
|
|
https://lafo.ssw.uni-linz.ac.at/pub/graal-external-deps/junit-4.12.jar
|
|
|
|
|
|
|
|
|
|
hamcrest-core-1.3.jar:
|
|
|
|
|
https://lafo.ssw.uni-linz.ac.at/pub/graal-external-deps/hamcrest-core-1.3.jar

Before running the tests you need to download these jars from above locations in build/<platform>/images/test/hotspot/jtreg/graal/
|
2019-05-21 19:29:47 +00:00
|
|
|
directory. You can use 'downloadLibs.sh' script which will try to download all these libs using wget.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Then you can run Graal unit test(s) using 'make run-test':
|
|
|
|
|
|
|
|
|
|
> make run-test TEST="compiler/graalunit/ApiTest.java" TEST_VM_OPTS="-server -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI"
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
If you want to use jtreg directly you need to say jtreg where to find external jars.
|
|
|
|
|
You can do it by passing additional option "-vmoptions:-Dgraalunit.libs=" or setting environment variable by using "-e:TEST_IMAGE_GRAAL_DIR=..."

Example:
|
2019-05-21 19:29:47 +00:00
|
|
|
> jtreg -vt -jdk:<TESTED_JDK> -vmoptions:"-server -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI"
|
|
|
|
|
-vmoptions:"-Dgraalunit.libs=build/<platform>/images/test/hotspot/jtreg/graal"
|
2018-06-29 00:07:34 +00:00
|
|
|
compiler/graalunit/UtilTest.java
|
|
|
|
|
|
|
|
|
|
To run Graal unit tests in Graal as JIT mode pass additional -vmoptions to jtreg:
|
|
|
|
|
-XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+TieredCompilation -XX:+UseJVMCICompiler -Djvmci.Compiler=graal
|
|
