The gotest parser used a bufio.Scanner to read its input, which
prevented us from reading lines larger than 64K.
In order to support reading larger lines, bufio.Scanner has been
replaced with bufio.Reader. The maximum line size has been increased to
4MiB and instead of returning an error when reading lines that exceed
the maximum size, we truncate that line and continue parsing.
Fixes#135
In some cases we may have captured some output for a package that didn't
have any tests. We should include it in the generated report as it may
contain useful information.
When we encounter a failure but there was not failing test, we create a
failing dummy test in the report. This is to prevent the failure from
being overlooked.
The case where the output contained a failing benchmark was not handled
correctly, resulting in a dummy test failure being added to the report
unnecessarily.
The reportBuilder has been updated to use the ordered output collector
to keep track of go test output. This makes it possible to include
benchmark output in the generated report and makes sure that output is
preserved when deleting subtest parents from the report.
Having multiple benchmarks for a single name is something specific to
the gotest output, so grouping benchmarks by name is not something that
belongs in the junit package.
The consequence of this is that any output emitted after the test or
benchmark result, will no longer belong to the last test. Instead it
will be appended to the global log. This is necessary to correctly
attribute output to the correct test or benchmark, for example in cases
where both tests and benchmarks appear.
In the past, Go test output printed test logs after the test result.
However, from Go 1.14 this behaviour was changed and test logs are now
printed before the test result.
With this commit, we effectively no longer support the old behaviour in
Go1.13 and earlier. The output will still appear in the generated
report, however it will no longer belong to the correct test.
