# VerifyZip Verifies all files in a zip archive. This approach combines [UseUniqueDirectory](/docs/naming.md#useuniquedirectory) with a target per file, to snapshot test all files in a zip archive. ```cs [Fact] public Task WithZip() => VerifyZip(zipPath); ``` ^{snippet source | anchor} ## Filtering ```cs [Fact] public Task WithZipFiltered() => VerifyZip( zipPath, include: filePath => filePath.FullName.Contains("Doc")); ``` ^{snippet source | anchor} ## Optional Info An optional `info` parameter can be supplied to add more context to the test. The instance passed will be json serialized. ```cs [Fact] public Task VerifyZipWithInfo() => VerifyZip( zipPath, info: "the info"); ``` ^{snippet source | anchor} ## FileScrubber `VerifyZip` has an optional parameter `fileScrubber` that allows file specific scrubbing: ```cs [Fact] public Task VerifyZipWithFileScrubber() => VerifyZip( zipPath, fileScrubber: (path, builder) => { if (Path.GetFileName(path) == "TextDoc.txt") { builder.Clear(); builder.Append("New text"); } }); ``` ^{snippet source | anchor} This applies to files where the extensions is a known text file as defined by [FileExtensions.IsText](https://github.com/VerifyTests/EmptyFiles#istext). ## Including structure Use `includeStructure: true` to include a file `structure.verified.md` that contains the zip directory structure. ```cs [Fact] public Task WithZipAndStructure() => VerifyZip(zipPath, includeStructure: true); ``` ^{snippet source | anchor} ## PersistArchive `persistArchive` determines whether the original ZipArchive or zip file should be preserved as a verified file. Defaults to false. ```cs [Fact] public Task WithZipAndPersistArchive() => VerifyZip(zipPath, persistArchive: true); ``` ^{snippet source | anchor} ## ArchiveExtension When using `persistArchive` the resulting verified archive file extension can be controlled using using the `archiveExtension` parameter. ```cs [Fact] public Task WithZipWithCustomExtension() => VerifyZip( File.ReadAllBytes(simpleZipPath), persistArchive: true, archiveExtension: "nupkg"); ``` ^{snippet source | anchor} The default extension is `zip`. Using the `VerifyZip` with the `Stream` overload, when the streams is a `FileStream` the extension of underlying file will be respected. Using the `VerifyZip` with the `string path` overload the extension of underlying file will be respected.
