Subject: fuse/runtests: added a --web-open option
X-Git-Url: https://git.rkrishnan.org/nxhtml.html?a=commitdiff_plain;h=8b9a26792048c4505db7e439c973f01b020d2f95;p=tahoe-lafs%2Ftahoe-lafs.git

fuse/runtests: added a --web-open option

similar to the --debug-wait option which causes the test harness to
pause at various stages of the process to facilitate debugging, this
option simplifies that debugging by automatically opening a web browser
to the root dir of that implementation's tests when tests are commenced.

in addition, if --web-open is specfied but --debug-wait is not, the
harness will still pause after running tests but before tearing down
the tahoe grid - this allows all tests to run to completion, but
provide a debugging hook to investigate the end state of the grid's
contents thereafter.
