// How to sort the entries in the table
entrySortMethod: "alphabetical", // || "least-coverage" || "most-coverage" || "largest-file-size" ||"smallest-file-size" || "uncovered-lines"
// The location of the istanbul coverage file.
coveragePath: "./coverage/coverage-summary.json",
// Alternatively, if you have multiple coverage summaries, you can merge them into one report
coveragePaths: ["./dir1/coverage-summary.json", "./dir2/coverage-summary.json"],
// You can also specify the format, instead of letting it be inferred from the file name
coveragePath: { path: "./coverage/lcov.info", type: "lcov" /* || "json-summary" */},
// Which set of files to summarise from the coverage file.
reportFileSet: "all", // || "modified" || "created" || "createdOrModified"
// Minimum coverage threshold percentages. Compared against the cumulative coverage of the reportFileSet.
threshold: {
statements: 100,
