Code coverage

http://www.ibm.com/developerworks/java/library/j-cq01316/index.html?ca=drs

There are different types of coverage measurements, but most tools focus on line coverage, also known as statement coverage. In addition, some tools report branch coverage. A test coverage measurement is obtained by exercising a code base with a test harness and capturing data that corresponds to code having been "touched" throughout the lifetime of the test process. The data is then synthesized to produce a coverage report. In Java shops, the test harness is commonly JUnit and the coverage tool is usually something like Cobertura, Emma, or Clover, to name a few.

Who We Are

Our volunteers teach basic software skills to researchers in science, engineering, and medicine. Founded in 1998, we are now part of the Mozilla Science Lab.

What We Do

We run bootcamps all over the world, and provide open access material for self-paced instruction. We also run a training program for people who'd like to help us teach.

How To Help

Like all volunteer organizations, we depend on you to help us help others. You can host a bootcamp, help create new teaching materials, or improve the tools we use.

Studies in mice and human patients suggest that microbial imbalances in the gut influence various social, emotional and anxiety-like behaviours. Interestingly, gastrointestinal (GI) problems are common in autism spectrum disorders (ASDs), which are associated with social interaction deficits and stereotypical behaviours. A new study in Cell provides evidence that alterations in commensal gut bacteria contribute to certain behavioural abnormalities in a mouse model of ASD, highlighting the potential benefit of probiotic therapies for some of the features of such disorders.

SQL EXPLAIN to analyse and improve SQL queries

Database SQL query is slow?

You can use MySQL's EXPLAIN to analyse the query, maybe the column of the WHERE clause needs to be indexed?

EXPLAIN SELECT tt.TicketNumber, tt.TimeIn,
               tt.ProjectReference, tt.EstimatedShipDate,
               tt.ActualShipDate, tt.ClientID,
               tt.ServiceCodes, tt.RepetitiveID,
               tt.CurrentProcess, tt.CurrentDPPerson,
               tt.RecordVolume, tt.DPPrinted, et.COUNTRY,
               et_1.COUNTRY, do.CUSTNAME
        FROM tt, et, et AS et_1, do
