Tsung is an open-source multi-protocol distributed load testing tool. It's written in Erlang , but don't let that dissuade you. Here are some simple steps to get started. Install Tsung. On Ubuntu, this is simply: sudo apt-get install tsung . Create a config file ( tsung.xml ): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYP... Beware of the dumptraffic attribute. You might want to set it to false for a real load test. Run the test: $ tsung -f tsung.xml start Starting Tsung "L... Generate the reports: $ cd /home/drxi/.tsung/log/20130923-1031 $ /usr... Open the report file in your browser: file:///home/drxi/.tsung/log/20130923-1031/report.html . For HTTPS testing change the server line to: <servers> <server host="192.168.80.160" port="...

The events mouseover and mouseout are fired when the mouse enters/leaves the element where the event handlers are registered, and any nested elements which do not handle these events (because of event bubbling ). The events mouseenter and mouseleave are fired only when the mouse enters/leaves the specified element. Nested elements do not come into play. This following is a test page. You need Firebug to view the console output. Or use the JavaScript Executor bookmarklet. If none of these are available, an alert will popup (but you won't be able to fully test with alert.). <!DOCTYPE HTML> <html> <head> <title>jQu... For the above test page, when you move the mouse through both the outer and inner areas of the mouseover/mouseout rectangle, the output is...

When you run automated Android tests with Eclipse or from the command line, you get text output, which isn't good for reporting purposes. If you run a large set of test cases with automated build, the text report isn't very helpful. Fortunately, Android CTS generates test reports in XML with accompanying XSL to make it look nice in a browser. To run your own tests with Android CTS: Download Android CTS Make a new directory MyRepository under android-cts , alongside the existing repository directory. Copy host_config.xml from repository to MyRepository Create directory plans under MyRepository , add a test plan ( MyTests.xml ): <?xml version="1.0" encoding="UTF-8"?> <TestPla... Create directory testcases under MyRepository . Copy TestDeviceSetup.apk from repository/testcases to MyRepository/testcases Under MyRepository/testcases , create a test...

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

From the nc man page: The nc (or netcat) utility is used for just about anything under the sun involving TCP or UDP. It can open TCP connections, send UDP packets, listen on arbitrary TCP and UDP ports, do port scanning, and deal with both IPv4 and IPv6. To bind to port 8080: nc -l 8080 To connect to the port above nc localhost 8080 Type something in either window it will be echoed in the other. To get the home page of google: echo -e -n "GET / HTTP/1.1\r\nHost:www.google.com\... To send email via SMTP: nc -C localhost 25 << EOF HELO host.example.com...

The code presented here is a simple implementation of a tab set. It is used to demo how a tab set could be implemented. The code is stand alone and does not depend on any JavaScript libraries. Multiple tab sets within the same page is supported. The HTML markup is fairly simple: Tabs sets are contained within a DIV element with class name "tabsContainer". Define a UL list for the tabs. Follow the UL list with equal number of DIVs for the tab contents. The Nifty Corners Cube technique is used to draw the rounded corners (original form, not the enhanced JavaScript form). HTML, CSS and JavaScript: <!doctype html> <html> <head> <style typ...

In this note I'll show you how to create and package a JSP custom tag. The purpose of this tag is to display a random splash image for a home page, among a set of images. We should be able to add or delete candidate splash images from the WAR archive without the need to change the JSP. This is the intended use of the tag: <%@ taglib uri="http://custom.tag.com/demo" prefix... In the above example you provide a set of images named splash*.png (e.g., splash1.png, spalsh2.png, ...), and the tag will pick a random one to display when the JSP is rendered. Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure ./pom.xml ./src ./src/main ./src/main/jav... pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... SplashTag.java package tagdemo; import java.util.ArrayList......
