Using JUnit in Eclipse

I think this is a JUnit question, but it may be relevant that I'm using it within Eclipse:
The main method in my test case looks like this:
     public static void main(String[] args) throws IOException {
          TestCase test = new LogParserTest("testReadFile");
          test.run();
     }Two strange things are happening:
1. This is running every test in LogParserTest -- not just "testReadFile".
2. My TestCase constructor is getting called twice (presumably b/c I have two tests. I'm sure these two behaviours are related.
Can someone tell me what's happening?
Here is the ctor for my TestCase:
     public LogParserTest(String str) throws IOException, FileNotFoundException {
          super(str);
          logParser = new SingleLogParser("C:/eclipse/workspace/TestFileIO/test/logs/testLog.txt");          
     }

AFAIK, you don't have to use a main method within a
testcase (well, at least when using Eclipse to run
JUnit tests). The fact why your ctor is called twice;
i dunno at this point.I did more research and found out. Turns out I don't need a ctor at all. Should have a setUp() method instead. And that is SUPPOSED to be called before each test, just as tearDown() is called after each test. Each test is supposed to be a unit (JUnit) and they are thus independent of one another. Basically, the behaviour is intened. My invocation in main is also abnormal, though it works. Better to call run on the class itself.

    what would the possible reason for that and how can i come out of it..

    the reason: the class is not in the classpath. Or the project's runtime classpath.
    Make sure it's added to the build path and if necessary exported all the way to your JUnit project.

  • How to compile Java files using Ant in Eclipse

    Hi All ,
    I would like to compile all Java files using Ant in Eclipse.Since am very new to Ant and Eclipse can someone help me to create a build.xml file and let me know how to compile all the java files.
    For ex , I have placed my java files inside the path C:\HEC\Terab.Initially the Terab folder holds 7 jar files which i had decompiled using JD compiler and placed the unzipped 7 folders (which contains the java files ).Now i have imported the HEC project into Eclipse using New ->Project ->Java Project.after importig it throwed me an error saying missing jar files.again i copied the jar files and placed inside Terab folder with other 7 folder.
    Now How i can compile the java files and convert in to class files.Then after compiling the files i will again need to jar all the 7 folder.
    Please tell me the steps i need to follow.How to write an build.xml file ? where i should keep it ? only one build.xml file is enough or should i write 7 build.xml file for each folder ? Please help me out...
    Thanks & Regards

  • How to test the JSP pages and sevlets using JUnit. ?

    How to test the JSP pages using JUnit. How to configure what are all the steps to execute the JUnit test cases.

    Hi xiepei,
    since you are using modbus, a simple error checking is implicit in the protocol and is the comparison between returned checksum and the calculated one on the received message: checksum errors, if any, are an effect of communications errors (you should have at least 2 bits changed and on particular patterns to have the checksum be calculated correctly!). You won't be able to calculate BER on them, but you can calculate PER (Packet Error Rate).
    Another flag for communication errors, on the other direction, is to intercept error messages from the device: if it fully implements modbus protocol, it should return some warning in case of error (I seem to remember that in some cases it returns the reveived message with some error bits added: please check in modbus documentation).

  • How to test servlet using Junit test????

    Hello everybody
    Does anybody know how to test an servlet class using Junit without using Cactus test . Is it possible to test a servlet using Junit without cactus test.Plz tell me the process how to test a servlet using Junit test .
    Regards
    srikant

    1) Do yoiu mean how to "run" your servlet code with sample parameter? This call manual testing with a sample run of you code. You need a web server(eg Tomcat), create a webapp with your servlet then deploy it there in order to run it.
    2) httpunit and junit are framework to write test case code that can be automated and repeatable. Plz read their doc.
    3) Your sample code me a very wrong way to retrieve and convert servlet parameters.
    Get a java toturial and servlet tutorial book and read it over the weekend. You need to get at least the basic.

  • How to run test cases in a jar file using junit?

    Hi,
    I want to run test cases in a jar file using junit and the jar file is not in the class path. I wrote the following code, but it does not work.
    import java.net.URL;
    import java.net.URLClassLoader;

    import junit.textui.TestRunner;
    public class MyTestRunner {

    Wouldn't it just be easier to put it on the classpath? You're trying to, anyway, with a URLClassLoader, albeit in an entirely unnecessarily complicated way

  • NIST conformance tests using JUnit

    I haven't seen anyone from Oracle on the [email protected] mailing list, so I'm posting this here just to let you guys know.
    I've been working on recasting the NIST DOM test suite for Java to use JUnit and posted an initial release last night.
    The tests can easily be run against the beta XDK's parser (or any other JAXP compliant parser), but there were a substantial number test errors and failures. Some of these may be due to test problems, but I'd guess most of them are legitimate. However, I do not have time or the motivation to investigate them.
    It does seem that you take the position that the XML declaration is treated as a processing instruction (like MSXML does) which will cause 3 tests to fail, but you can adjust the tests to accept this using
    -Dnet.sourceforge.xmlconf.domunit.acceptXMLDeclPI=true
    I've made the source for my JUnit-hosted deriviatives of the NIST test suite available at http://xmlconf.sourceforge.net. You can either download the combined source and binary
    zip file from http://sourceforge.net/project/showfiles.php?group_id=8114&release_id=31676
    or you can access the source through the CVS (http://sourceforge.net/cvs/?group_id=8114)
    The tests run using JUnit 3.5 and can test JAXP 1.0 or JAXP 1.1 compliant DOM parsers.
    Xerces-J 1.3.1 does not report any test failures, crimson.jar and the other parser tested
    had a moderate amount of test failures, but no investigation has been performed to
    determine if those failures were problems with the tests or actual non-conformances
    with the spec.
    A JBuilder 4 .jpx project and an Ant 1.2 build.xml file are provided.

  • Accessing resource files inside Jar using Fat Jar Eclipse plugin

    Hi,
    I want to develop single JAR file that uses a set of other JAR libraries. I am using Fat Jar Eclipse plugin. It works fine. However, I have problem to access resources files (i.e. rdf file) using relative path from my classes. Is there any idea how can I pack, set classpath and use relative path in order to make it works.
    Thanks

    I have solved this problem. The problem was in a way how I have trying to access it. It should be like:

Especially in the case of Maven that is highly recommended as it has a very steep learning curve. I wrote an article about getting started with Maven and about using Maven in Eclipse that you could use as a base for your research:
    http://entjavastuff.blogspot.com/2010/06/maven2-copy-pastable-template.html
    http://entjavastuff.blogspot.com/2011/10/using-maven-in-eclipse.html
    But I stress that point: use it as a base for your research; there is no real step by step guide that will make you understand, it will only show you what to do in a very specific case which will not match what you want to do. As for your web services question, that's a simple Google query. "maven jax-ws". That should point you to the Maven plugin documentation.

  • Using javadocs in Eclipse

    My team and I are trying to use javadocs in eclipse to document our source codes. I have used the javadoc generator in eclipse but do I have to manual comment in the details of the javadoc such as parameters, and a summary of the method? Is it possible to hide the javadocs? We just want to have a seperate folder for javadocs where we can view/edit the javadocs and still have no javadocs or comments within our code. anyone got suggestions????

    Hi,
    Well, Eclipse adds nothing special here. But you have actually an interesting idea...
    Some (long) time ago I used to hear that it was hailed as a big progress a possibility to store all actual descriptions along with the Java code and to generate by them the entire finished documentation automatically. But now, it seems, you want to go back in time...
    I believe, the standard Javadoc is unable to support anything like this.
    However, if you still want to use Javadoc in such an arrangement so as to generate the overall documentation skeleton (as well as to employ Javadoc's HTML output engine), you will need to develop your own doclet or a taglet, at least.
    For instance, you could introduce some special tags using which you would specify the locations of your description files (directly or using some identifiers). Then, your taglet would process those tags, read those descriptions from the files and feed them to Javadoc.
    Another way is to imply the locations of your description files from the program element (i.e. class, method or field) being processed by Javadoc. The doclet API provides all necessary information together with the location of a Java source file. So you could use it to find your custom description files somewhere nearby it.
    I suggest also to look at this product:
    http://www.filigris.com/products/docflex_javadoc/
    This is a highly customizable Javadoc doclet. More precisely, this is a system for rapid development of professional quality doclets from scratch (with the support of both framed/single-file HTML and RTF output). If you are prepared to buy some number of licenses, we could very much customize this product for your needs. So, your task will be solved with no problem.

    Can you tell me how to use Tomcat using Eclipse?
    Whether we have to plug-in Tomcat in Eclipse?
    I'm using Eclipse3.1.1 Version.
    Thanks,
    Hari

    you can use "com.sysdeo.eclipse.tomcat_3.1.0" plugin. Just download the zip file and expand it in plugin folder of eclipse. I am using it on ecipse 3.1.2 it works fine.
    By the way you need to set certain parameters in Eclispe.
    GO to windows-preferences-java
    Installed JREs - add the path of your j2sdk1.4.(eg.c:j2sdk1.4.2_11)
    then Go to windows--preferences--tomcat-
    advanced - fill your tomcat base
    JVMSettings - JRE drop down box select the j2sdk you added
    JVMSettings - classpath - add tools.jar from your j2sdk lib folder
    JVMSettings - Boot ClassPath - add rt.jar from your jre lib folder
    SourcePath
    Select your java project you are working with
    Then click ok.
    Try to run eclipse in clear mode.
    Please let me know if this worked. I also did the same procedure and It is working fine.
