如何在Nunit中使用文件Asserts并检查文件是否存在

Question

如何在Nunit中使用文件Asserts并检查文件是否存在。需要一些清晰和基本理解的例子。任何人都可以帮帮我

Answer 1

You should use:

var fileName = @"C:\somedirectory\somefile.txt";

Assert.IsTrue(File.Exists(fileName));

FileAssert can be only used for comparison of two actual files from disc of from some abstract stream

Answer 2

As of NUnit 2.9.7 (released just before this question was asked) you can use FileAssert.Exists(@"C:\\somedirectory\\somefile.txt"); .

Answer 3

The new Framework allows this also:

Ex. FileAssert.IsEqual(FileName1, FileName2);
    FileAssert.IsNotEqual(FileName1, FileName2);

To compare 2 Files.

Answer 4

May be help you as below: C# You need to deploy your files on your UT project.

[DeploymentItem("file1.xml")] Copies file1.xml from the build output directory to the deployment directory. [DeploymentItem(@"Testfiles\\")] Copies all the files and folders in the Testfiles folder from the build output folder to the deployment folder. Subfolders are replicated in the deployment folder. [DeploymentItem("file2.xml", "DataFiles")] Creates a folder named DataFiles in the deployment folder, and copies file2.xml from the build output folder to DataFiles.

Assert.istrue(File.exist("your file"));

Answer 5

NUnit 3.0 includes a FileOrDirectoryExistsConstraint .

var filePath = "C:\pathtofile.txt";
Assert.That(filePath, Does.Exist);
