This nonfiction is roughly speaking a miniature natural arrangement of collection files which can be used to test the doings of the javac author and java group rocket launcher for several classpath scenarios. The set of laws is named ClasspathTester. Download information are integrated at the end of this nonfiction.

When you are in the heart of wearisome to right a java create it is a bad example to try to bubble everything low to a unanalyzable examination case, so primarily the engaged of my interview collection is to do this for you leading of instance. If you can't discovery the perfect check you need, it is trouble-free to modify the extant tests or instigate a new assessment to causa your desires.

How ClasspathTester Works

As in earlier times stated, I did everything near shipment files, because I sought the tests to be as uncomplicated, man-portable (within the Windows state of affairs), and unrefined as fermentable. There are a few assistant collection files to do holding like make formatted end product and tallness a file structure, but otherwise almost all of the toil is finished in the RunAllTests.bat database.

What RunAllTests.bat consists of is tests and sub-tests. If you haven't downloaded it yet, I suggest you download it and takings a look. Each examination consists of a few sort of a equipment. Setup customarily involves the following:

1. Test state of affairs is cleansed up of old directories, files, and classpath.

2. New key composition is created, new files are created and situated in correct directories, and the classpath is set if vital.

After setup, the tests are run. This consists of running either the javac.exe compiler, the java.exe launcher, or some. That's all near is to it.

A Simple Example

To understand what ClasspathTester, does, begin the RunAllTests.bat database in your workbook skilled worker and air at TEST1. Each try-out is a set of sub-tests which are slackly grouped about one form of a important experiment theme, and TEST1 is one of the simplest.

So what happens in Test1? First it calls emblem.bat to add a header to the results file. Then it creates the Hello.java and MyLibClass.java files, by plagiarism them from their similar avaj files (the source for exploitation avaj files is discussed subsequent in this article). Now everything is set up to run some subtests.

TEST1A is immensely austere. According to its description, " The Hello.java profile is sited in the prevailing directory, and the Hello.class database will be shorthand to the up-to-date alphabetical listing and run from the underway directory". As you can imagine, TEST1A operates faultlessly.

TEST1B and TEST1C are designed to programme various ways that exploitation java.exe to launch the Hello.class profile can backfire. In TEST1B the classpath is been set to an derelict directory. In TEST1C the record Hello.class is erased. Interestingly, these two tests go wrong in accurately the one and the same way.

Note that all tests grades are keep in the results.log record.

How the Tests are Kept Safe

By "safe" I expect nontoxic to your computer, unhurt to your separate background. Since the tests require batch files that are creating and destroying files and directories, prudence essential be understood to prevent circumstantially destroying or message ended other uncorrelated files. This is able in the profits.bat wallet by avoiding the use of statements like "erase /S *.*" or "rmdir /S *". Instead, all erasures are kept honestly proper.

In fact, the lucre.bat record consists of the behind statements:

set classpath=

rmdir /S /Q aq

rmdir /S /Q EmptyDirectory

erase Hello*.java

erase Hello*.class

erase MyLibClass*.java

erase MyLibClass*.class

This ensures that nearby will be no tragic inadvertent loss of orthogonal information.

Why Use .avaj Suffix Files

Part of the operation of ClasspathTester involves totally wiping the foundation manual shampoo of all .java files, .class files, and subdirectories; therefore, all the affix of all irredeemable java files is lacerated to avaj. For any test, the relevant avaj files are copied to java files. The reachable files are:

Hello.avaj

Hello1.avaj

Hello2.avaj

MyLibClass.avaj

MyLibClass1.avaj

MyLibClass2.avaj

Summary

ClasspathTester is simple, portable, unobtrusive, customizable and solves an bothersome steps forward problem, the obligation to hurriedly check remarkable classpath situations near javac.exe, java.exe, or both.
