JProbe

1. JProbe

• Use JProbe Profile– identify method and line level performance bottlenecks

• Use JProbe Memory Debugger– investigating memory leaks and garbage collection activity

• Use JProbe Threadalyze– finding thread deadlocks and stalls

• Use JProbe Coverage– measuring code coverage after testing

1.1 JProbe Profiler

• Hunt Down Performance Bottlenecks– helps developers quickly diagnose performance bottlenecks in Ja

va code. – With highly accurate diagnostics, line-by-line results

• Improved Call Graph– JProbe Profiler Call Graph – encapsulates the valuable information

• Application Server Configuration Wizard– Integrating testing tools with application servers environments

1.1 JProbe Profiler

• Benefits: – Pinpoint performance bottlenecks down to the

line of code with advanced Call Graph – Zero in on critical code with advanced filtering – Analyze your performance using nine different

metrics – Automate the collection of performance

information using triggers – Perform local or remote analysis sessions without

any code changes – Generate reports and share information about

your application performance

1.2 JProbe Memory Debugger

• Find and Fix Memory Leaks Now– helps developers quickly pinpoint memory leaks in Java code and reduce

application memory usage.– visualize complex data on memory usage and memory leaks

• Benefits JProbe Memory Debugger provides include: – Diagnosis and resolution of memory leaks – Identification and elimination of expensive memory recycling with the Gar

bage Monitor – Dramatic improvement in memory consumption and application performa

nce – Comparing memory usage before and after critical code changes with sn

apshot differencing – Automation of the collection of memory analysis data with triggers - savi

ng you valuable time – Generation reports and metrics on memory use and Garbage Collection

1.3 JProbe Coverage

• Is Your Code Covered?– To ensure accurate Java applications, Quality Assuran

ce professionals and developers need to know • how much of the code has been tested• where to find any untested code.

– JProbe Coverage • you locate untested code• measure precisely how much code has been exercised.• The result is a higher quality application in a shorter peri

od of time.

1.3 JProbe Coverage

• JProbe Coverage 5.0– dramatically improved analysis time– providing users with up to factor of 10 improvement in

speed– Profiling and code coverage sessions are particularly i

mproved

– New to JProbe Coverage 5.0• the ability to generate class-level coverage reports• to the line and method-level reports offered by previous

versions.

1.3 JProbe Coverage

• With JProbe Coverage you can: – Identify and measure untested lines of code, methods

and classes – Ensure test runs are accurate and comprehensive – Merge total coverage data from multiple runs of your p

rogram – Browse, share and print results in HTML, text, XML, cs

v and PDF – Automate your coverage analysis as part of your nightl

y build and regression testing – Reduce Testing Time with JProbe Coverage

1.3 JProbe Coverage

• Reduce Testing Time with JProbe Coverage

– Testing and Quality Assurance (QA) • expensive and time consuming• QA to find

– problems– inform developers– wait for fixes– retest

• the frequency of the bugs decreases sufficiently

1.3 JProbe Coverage– JProbe Coverage helps

• developers ensure a basic level of testing before sending the application into formal QA.

• This process reduces the overall cost of delivering an application

• helps you deliver higher quality applications in a shorter period of time.
