我正在an R project is tested with Travis CI工作。当我在本地运行testthat测试时，所有测试都通过。当这些测试在Travis CI上运行时，一些测试失败了。
问题是我无法看到测试运行后出现的详细错误消息。
我确实看到了＆＃39;顶部＆＃39;特拉维斯的错误：
ERROR

我没有看到＆＃39;底部＆＃39; Travis CI上的错误消息。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.
我希望/希望我能抓住下半部分＆＃39;在特拉维斯CI。我希望/希望有一个日志文件写在某处，但我找不到在哪里。
[编辑：添加此内容]请注意，有时我会看到输出，如下面的示例输出。这可能是一个单独的问题，但我也很乐意看到那里的所有输出线：
Last 13 lines of output:
