如何从Makefile运行nyc merge? [英] How do I run nyc merge from Makefile?

问题描述

我已经用Jasmine单元测试继承了JS代码库.测试框架使用karma和instanbul-combine来获取代码覆盖率.看来istanbul-combine不能与当前的节点模块一起使用，而且不再维护:建议的替代品是nyc.我在用Makefile中的nyc替换istanbul-combine时遇到问题.

I've inherited a JS code base with Jasmine unit tests. The testing framework uses karma and instanbul-combine to get code coverage. It seems istanbul-combine isn't working with present node modules, and besides is no longer maintained: the recommended replacement is nyc. I'm having trouble replacing istanbul-combine with nyc in the Makefile.

这是我尝试合并数据的尝试(甚至还没有尝试获取报告):

Here's are my attempts at merging the data (not even trying to get a report yet):

#1

@for dir in $(shell ls -d coverage/*/); do \
    echo "Merging $${dir}"; \
    npx nyc merge $${dir} coverage-final.json; \
done

#2

npx nyc merge coverage coverage-final.json

#3

npx nyc merge --include coverage/*/ coverage-final.json

coverage数据位于coverage/*/coverage-final.json中，但是这些尝试均未能成功将其合并到结果文件coverage-final.json中.

The coverage data is in coverage/*/coverage-final.json, but none of these attempts succeeds in mergeing it into the result file coverage-final.json.

使用#1，我可以肯定它实际上只是将一组结果合并到结果文件中.对于#2，会有一个错误.但是，如果我将该命令放在外壳CLI中，则结果文件中将不会放置任何内容.

With #1, I'm pretty sure it's only actually merging a single set of results into the result file. With #2, there's an error; but if I put that command in the shell CLI, nothing is put into the result file.

使用#3，至少没有错误，但是仅合并了一个coverage文件.

With #3, at least there's no error, but only one of the coverage files is merged.

这是我要替换的原始Makefile行:

Here's the original Makefile line that I'm replacing:

PATH=$(PROJECT_HOME)/bin:$$PATH node_modules/istanbul-combine/cli.js \
    -d coverage/summary -r html \
    coverage/*/coverage-final.json

推荐答案

我在Makefile中编写了一个小脚本，用于将coverage-final.json文件从coverage目录的子目录复制到coverage目录本身，然后将它们合并到JS主目录中的coverage-final.json文件中.

I wrote a little script in the Makefile to copy the coverage-final.json files from the child directories of the coverage directory to the coverage directory itself, and then merge them into a coverage-final.json file in the main JS directory.

@cd coverage; \
 for dir in $(dir */coverage-final.json); do \
        fn="$${dir}coverage-final.json"; \
    newName="$${dir::-1}.json"; \
    echo "cp $${fn} $${newName}"; \
    cp $$fn $$newName; \
done;
npx nyc merge coverage coverage-final.json

各个覆盖率文件的新文件名取自它们所来自的目录的名称.

The new filenames of the individual coverage files are taken from the name of the directories from which they come.
