ScalaTest is a free, open-source testing toolkit for Scala and Java programmers.
Official Website: http://www.scalatest.org/
Please visit Download and Setup for download and setup instructions.
Please visit Quick Start for steps to get started quickly.
The followings are needed for building ScalaTest:
- JDK 8
- SBT 1.2.8
use the following SBT options instead:
SBT_OPTS="-server -Xms512M -Xmx3000M -Xss1M -XX:+UseConcMarkSweepGC -XX:NewRatio=8"
Building and Running Tests
This command will build and run the regular tests:
$ sbt test
To run generated all tests, you'll need to increase maximum heap size to at least -Xmx5000M, and use this command instead:
$ rm -rf gentests $ sbt gentests/test
You can also run different groups generated tests separately:
$ rm -rf gentests $ sbt genMustMatchersTests1/test $ sbt genMustMatchersTests2/test $ sbt genMustMatchersTests3/test $ sbt genMustMatchersTests4/test $ sbt genGenTests/test $ sbt genTablesTests/test $ sbt genInspectorsTests/test $ sbt genInspectorsShorthandsTests1/test $ sbt genInspectorsShorthandsTests2/test $ sbt genTheyTests/test $ sbt genContainTests1/test $ sbt genContainTests2/test $ sbt genSortedTests/test $ sbt genLoneElementTests/test $ sbt genEmptyTests/test
What it does is simply switch to gentests project and run test.
To run scala-js tests:
$ sbt scalatestAppJS/clean $ sbt scalacticTestJS/test:compile $ sbt scalacticTestJS/test $ sbt scalatestTestJS/test:compile $ sbt scalatestTestJS/test
To run scala-native tests:
$ sbt -Dscalatest.skip.jdk.check=true ++2.11.12 scalatestAppNative/clean $ sbt -Dscalatest.skip.jdk.check=true ++2.11.12 scalacticTestNative/test:compile $ sbt -Dscalatest.skip.jdk.check=true ++2.11.12 scalacticTestNative/test $ sbt -Dscalatest.skip.jdk.check=true ++2.11.12 scalatestTestNative/test:compile $ sbt -Dscalatest.skip.jdk.check=true ++2.11.12 scalatestTestNative/test
You can build examples project using this command:
$ sbt examples/compile
You can package the ScalaTest JAR file using this command:
$ sbt package
The resulting JAR file will be produced in target/scala-2.11/.
You can also publish it to your local Ivy repository using this command:
$ sbt publishLocal
Or publish it to local maven repository using this command:
$ sbt publishM2
To publish to Sonatype, you first need to make sure you have the following:
- A GPG client is installed on your command line path. For more information, please refer to GNU Privacy Guard Website.
- You have created your GPG keys and distributed your public key to hkp://pool.sks-keyservers.net/. For more information, please refer to How To Generate PGP Signatures With Maven.
- You have been granted the right to publish using org.scalatest and org.scalactic domain.
By default, ScalaTest build will read your Sonatype credentials from ~/.ivy2/.credentials, which is a properties file that looks like this:
realm=Sonatype Nexus Repository Manager host=oss.sonatype.org user=xxxxxxxx password=xxxxxxxx
You can use SCALATEST_NEXUS_LOGIN and SCALATEST_NEXUS_PASSWORD environment variables to override Sonatype credentials.
For signing, ScalaTest build will use ~/.gnupg/secring.gpg by default and prompt for GPG passphase if required. Alternatively you can use SCALATEST_GPG_FILE to use a different GPG file, and use SCALATEST_GPG_PASSPHASE to provide GPG passphase to avoid input prompt.
If you would like to export a particular private key into a separate GPG file, you can use the following command:
$ gpg --export-secret-keys firstname.lastname@example.org > example-secret-key.gpg
With Sonatype credentials and GPG file in place, you can now publish to Sonatype.
Before publishing any patch release, binary compatibility with previous version should be checked:
$ sbt ++2.11.12 scalactic/package scalactic/mimaReportBinaryIssues $ sbt ++2.11.12 scalatest/package scalatest/mimaReportBinaryIssues $ sbt ++2.11.12 scalacticJS/package scalacticJS/mimaReportBinaryIssues $ sbt ++2.11.12 scalatestJS/package scalatestJS/mimaReportBinaryIssues $ sbt ++2.10.7 scalactic/package scalactic/mimaReportBinaryIssues $ sbt ++2.10.7 scalatest/package scalatest/mimaReportBinaryIssues $ sbt ++2.10.7 scalacticJS/package scalacticJS/mimaReportBinaryIssues $ sbt ++2.10.7 scalatestJS/package scalatestJS/mimaReportBinaryIssues $ sbt ++2.12.6 scalactic/package scalactic/mimaReportBinaryIssues $ sbt ++2.12.6 scalatest/package scalatest/mimaReportBinaryIssues $ sbt ++2.12.6 scalacticJS/package scalacticJS/mimaReportBinaryIssues $ sbt ++2.12.6 scalatestJS/package scalatestJS/mimaReportBinaryIssues $ sbt ++2.13.0-RC1 scalactic/package scalactic/mimaReportBinaryIssues $ sbt ++2.13.0-RC1 scalatest/package scalatest/mimaReportBinaryIssues $ sbt ++2.13.0-RC1 scalacticJS/package scalacticJS/mimaReportBinaryIssues $ sbt ++2.13.0-RC1 scalatestJS/package scalatestJS/mimaReportBinaryIssues
To publish scalactic, scalatest and scalatest-app use the following command:
$ export SCALAJS_VERSION=0.6.27 $ sbt ++2.10.7 clean publishSigned "project scalatestAppJS" clean publishSigned $ sbt ++2.11.12 clean publishSigned "project scalatestAppJS" clean publishSigned $ sbt ++2.12.8 "project scalatestApp" clean publishSigned "project scalatestAppJS" clean publishSigned $ sbt ++2.13.0-RC1 "project scalatestApp" clean publishSigned "project scalatestAppJS" clean publishSigned $ export SCALAJS_VERSION=1.0.0-M7 $ sbt ++2.11.12 "project scalatestAppJS" clean publishSigned $ sbt ++2.12.8 "project scalatestAppJS" clean publishSigned $ sbt ++2.13.0-RC1 "project scalatestAppJS" clean publishSigned
To publish scalactic, scalatest and scalatest-app (for Scala-native version 2.11, and make sure you're on Java 8) to Sonatype, use the following command:
$ sbt ++2.11.12 "project scalatestAppNative" clean publishSigned
