Module frame_support::testing_prelude

Prelude to be used for pallet testing, for ease of use.

Modules

• bounded_btree_map
  Traits, types and structs to support a bounded BTreeMap.
• bounded_vec
  Traits, types and structs to support putting a bounded vector into storage, as a raw value, map or a double map.

Macros

• assert_eq_error_rate
  Copied from sp-runtime and documented there.
• assert_err
  Assert an expression returns an error specified.
• assert_err_ignore_postinfo
  Assert an expression returns an error specified.
• assert_err_with_weight
  Assert an expression returns error with the given weight.
• assert_error_encoded_size
  Assert that the maximum encoding size does not exceed the value defined in MAX_MODULE_ERROR_ENCODED_SIZE during compilation.
• assert_noop
  Evaluate an expression, assert it returns an expected Err value and that runtime storage has not been mutated (i.e. expression is a no-operation).
• assert_ok
  Panic if an expression doesn’t evaluate to Ok.
• assert_storage_noop
  Evaluate any expression and assert that runtime storage has not been mutated (i.e. expression is a storage no-operation).
• bounded_btree_map
  Build a bounded btree-map from the given literals.
• bounded_vec
  Build a bounded vec from the given literals.
• parameter_types
  Create new implementations of the Get trait.

Traits

• Get
  A trait for querying a single value from a type.
