"test" as part of the name is redundant, and spaces aren't recommended.
Add a padding for two digits, so that tests with more than a handful of
subtests still print in a nice way.
Many consecutive calls to Run can be collapsed into a single call. While
at it, make the error handling style more consistent. Overall removes 70
lines of repetitive code.
t.Parallel effectively fires off a goroutine, so we can't use the test
range variable directly. That can result in different subtests using the
same test case data, causing sporadic failures, or some test cases
rarely being actually tested.
This was uncovered while stress-testing the test suite for an unrelated
refactor.
While at it, one test case in TestMouseClickNode was incorrect.
contextmenu fires on a right click, so ModifierNone won't fire it. This
wasn't caught before, as this test case was almost never ran. After the
data race fix, the test case failed consistently, before being fixed.
The navigate sleeps can be replaced by appropriate wait actions.
Some other tests don't need any sleeps at all. This might be because
work is done synchronously now; I haven't been able to get test flakes
after hundreds of test runs with flags like -parallel=32 -count=200.
First, we want all of the functionality in a single package; this means
collapsing whatever is useful into the root chromedp package.
The runner package is being replaced by the Allocator interface, with a
default implementation which starts browser processes.
The client package doesn't really have a place in the new design. The
context, allocator, and browser types will handle the connection with
each browser.
Finally, the new API is context-based, hence the addition of context.go.
The tests have been modified to build and run against the new API.
The subtests were almost all marked as parallel, but that's not enough.
That only makes the subtests run in parallel with other subtests within
the same tests, not with any other test.
Since none of the tests make use of globals nor require the entire
program to themselves, properly run all the tests in parallel.
Speeds up 'go test' on my 8-core laptop from an average of ~130s to an
average of ~50s. Many tests hit timeouts and have sleeps, so we want to
avoid running those sequentially whenever possible.
