我正在开发一个使用 Travis CI 测试的R 项目。当我在本地运行测试时，所有测试都通过了。当这些测试在 Travis CI 上运行时，一些测试会失败。testthat
问题是我看不到测试运行后出现的详细错误消息。
我确实看到了 Travis 错误的“顶部”：
ERROR

我没有在 Travis CI 上看到错误消息的“底部”。我在这里举了一个例子，所以你知道我希望看到什么：
Failed -------------------------------------------------------------------------
1. Failure: alignment is added (@test-add_alignments.R#49) ---------------------
add_alignments(filename, verbose = TRUE) did not throw an error.
我期望/希望我能掌握 Travis CI 的“下部”。我希望/希望某处有一个日志文件，但我找不到在哪里。
[编辑：添加此] 请注意，有时我会看到类似下面示例输出的输出。这可能是一个单独的问题，但我也很想在那里看到所有输出行：

mcmc_chainlength = mcmc_chainlength, rng_seed = new_seed, skip_if_output_present = skip_if_output_present,
verbose = verbose)
