`solver_helpers`#

Helpers for testing the solver.

Classes#

`SimpleEnvironment`	Helper environment object.
`SolverTests`	Tests for `conda.core.solve.Solver` implementations.

Functions#

`index_packages`(num)	Get the index data of the `helpers.get_index_r_*` helpers.
`package_string`(record)
`package_string_set`(packages)	Transforms package container in package string set.
`package_dict`(packages)	Transforms package container into a dictionary.
`empty_prefix`()
`temp_simple_env`(→ SimpleEnvironment)

index_packages(num)#: Get the index data of the helpers.get_index_r_* helpers.

package_string(record)#

package_string_set(packages)#: Transforms package container in package string set.

package_dict(packages)#: Transforms package container into a dictionary.

class SimpleEnvironment(path, solver_class, subdirs=context.subdirs)#

Helper environment object.

property _channel_packages#: Helper that unfolds the repo_packages into a dictionary.

REPO_DATA_KEYS = ('build', 'build_number', 'depends', 'license', 'md5', 'name', 'sha256', 'size', 'subdir',...#

solver(add, remove)#: Writes repo_packages to the disk and creates a solver instance.

remove(*specs, as_specs=False)#

_package_data(record)#: Turn record into data, to be written in the JSON environment/repo files.

_write_installed_packages()#

_write_repo_packages(channel_name, packages)#: Write packages to the channel path.

empty_prefix()#

temp_simple_env(solver_class=Solver) → SimpleEnvironment#

class SolverTests#
