module documentation

Helpers to compile Java and run unit tests with coverage.

Function	`classForPath`	Converts a path relative to root directory to a class name.
Function	`compileJava`	A default java compilation command. Kept simple. If you need a more elaborate setup, it is easy enough to write your own, rather than this function being extremely configurable and configure it.
Function	`jacocoReport`	Creates a coverage report from the output of `jacocoRunJunit4`.
Function	`jacocoRunJunit4`	Runs junit4 tests with the default `JunitCore` class.
Constant	`_PATHSEP`	Undocumented

def classForPath(classpathEntry: Path, p: Path) -> str: ¶

Converts a path relative to root directory to a class name.

For example if classpathEntry is build/test and the p is build/test/my/package/Dodo.class, the result is my.package.Dodo.

Parameters
classpathEntry:`Path`	a directory containing compiled classes
p:`Path`	a `*.class` file within `classpathEntry`

Returns
`str`	Undocumented

def compileJava(targetPath: os.PathLike, srcPath: os.PathLike, *classpath: Path): ¶

A default java compilation command. Kept simple. If you need a more elaborate setup, it is easy enough to write your own, rather than this function being extremely configurable and configure it.

Parameters
targetPath:`os.PathLike`	a `Path` where to drop the compiled files
srcPath:`os.PathLike`	the source files directory
*classpath:`Path`	classpath members

def jacocoReport(targetPath: Path, jacocoCli: Path, jacocoData: Path, classFiles: Path, sourceFiles: Path): ¶

Creates a coverage report from the output of jacocoRunJunit4.

Parameters
targetPath:`Path`	the directory where to place the coverage html files
jacocoCli:`Path`	the jar `org.jacoco.cli...jar`.
jacocoData:`Path`	the output of `jacocoRunJunit4`
classFiles:`Path`	the compiled classes classpath
sourceFiles:`Path`	directory with the source files

def jacocoRunJunit4(targetPath: Path, testClassesPath: Path, testClassRe: str | re.Pattern, jacocoJar: Path, *classpath: Path): ¶

Runs junit4 tests with the default JunitCore class.

Parameters
targetPath:`Path`	the path of the coverage data to produce by running with jacoco
testClassesPath:`Path`	a `Path` representing a classpath entry for test classes
testClassRe:`str \| re.Pattern`	a regular expression or compiled pattern which has to be matched by `.class` files on the `testClassesPath` to be included as a test class. Classes with a `$` in the name are always excluded. If there are no helper classses on the classpath, just use `.`, otherwise, depending on your convention, `^Test.` or `.*Test[.]class$` may be what you need. Only the file name, without any leading path name, will be searched with the pattern.
jacocoJar:`Path`	the jar `org.jacoco.agent...jar`, not going on the class path
*classpath:`Path`	further classpath entries, i.e. classes, junit jar, etc.
