covWrite

Arguments

"html"

exports the coverage data as HTML files

"binary"

store the coverage data as binary for later use

dir

output directory as a string

binaryFile

stored binary filename as a string

Description

This command is used to export, store or "load and export" runtime instrumentation data to the file system. The major usage is to export the current runtime information to HTML files on a directory using covWrite("html", "TMPDIR/coverage").

This command is used to export, store or "load and export" runtime instrumentation data to the file system.

Basic example

covStart(isempty)                      // instrument isempty by macro value
for i=1:1e5; isempty(i); end           // run
covWrite("html", "TMPDIR/coverage")    // write runtime information to a directory
covStop();                             // remove any instrumentation

Binary exemple

covStart(isempty)
for i=1:1e5; isempty(i); end
covWrite("binary", "TMPDIR/isempty1")  // write runtime information
covStop();                             // clear instrumentation

covStart(isempty)
for i=1:1e5; isempty(string(i)); end
covWrite("binary", "TMPDIR/isempty2")  // write other runtime information
covStop();

covMerge(["TMPDIR/isempty1" "TMPDIR/isempty2"], "TMPDIR/isempty") // merge them
covWrite("html", "TMPDIR/isempty", "TMPDIR/coverage") // render the information as HTML
