Building ScalaTest

Pre-Requisites

The followings are needed for building ScalaTest:

JDK 6, 7 or 8
SBT 0.13.2

for JDK 6 or 7, use the following options in your SBT launch file:

SBT_OPTS="-server -Xms512M -Xmx3000M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewRatio=8 -XX:MaxPermSize=512M"

for JDK 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 -Xmx5000M, and use this command instead:

$ sbt gentests/test

You can also run different groups generated tests separately:

$ 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
$ sbt genSafeStyleTests/test

What it does is simply switch to gentests project and run test.

Building Exmaples

You can build examples project using this command:

$ sbt examples/compile

Packaging

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

Publishing

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 example@example.com > example-secret-key.gpg

With Sonatype credentials and GPG file in place, you can now publish to Sonatype.

To publish scalactic, scalatest and scalatest-app (for Scala and Scala-js, version 2.11 and 2.10, and make sure you're on Java 6) to Sonatype, use the following command:

$ sbt clean publishSigned "project scalatestAppJS" clean publishSigned ++2.10.6 "project scalatestApp" clean publishSigned "project scalatestAppJS" clean publishSigned

To publish scalactic, scalatest and scalatest-app (for Scala and Scala-js, version 2.12, and make sure you're on Java 8) to Sonatype, use the following command:

$ sbt ++2.12.0-M5 clean publishSigned "project scalatestAppJS" clean publishSigned
