How do I specify a custom manifest file name for snyk test?

You can specify a non-standard file name for a project by adding a couple of parameters to the command:

--file=<file name>

and

--package-manager=<package manager>

The options for <package manager> are currently as follows:

• rubygems: 'RubyGems'
• npm: 'npm'
• yarn: 'Yarn'
• maven: 'Maven'
• pip: 'pip',
• sbt: 'SBT',
• gradle: 'Gradle',
• golangdep: 'dep (Go)',
• gomodules: 'Go Modules',
• govendor: 'govendor',
• nuget: 'NuGet',
• paket: 'Paket',
• composer: 'Composer',

For example:

snyk test --file=requirements_dev.txt --package-manager=pip
