+Feature: Repositories with cost
+
+
+Background: Use repository with cost 1000
+  Given I use repository "dnf-ci-priority-1" with configuration
+        | key      | value |
+        | cost     | 1000  |
+
+
+Scenario: Install and reinstall RPM from the lower-cost repository
+   When I execute dnf with args "--nogpgcheck install flac --repofrompath=cost_900,{context.scenario.repos_location}/dnf-ci-priority-1 --setopt=cost_900.cost=900 --repofrompath=cost_1100,{context.scenario.repos_location}/dnf-ci-priority-1 --setopt=cost_1100.cost=1100"
+   Then the exit code is 0
+    And Transaction is following
+        | Action        | Package                                   |
+        | install       | flac-0:1.3.3-2.fc29.x86_64                |
+   When I execute dnf with args "repoquery --installed flac --qf='%{{name}} %{{from_repo}}'"
+   Then the exit code is 0
+    And stdout contains "flac cost_900"
+   When I execute dnf with args "--nogpgcheck reinstall flac --repofrompath=cost_900,{context.scenario.repos_location}/dnf-ci-priority-1 --setopt=cost_900.cost=900 --repofrompath=cost_1100,{context.scenario.repos_location}/dnf-ci-priority-1 --setopt=cost_1100.cost=1100"
+   Then the exit code is 0
+    And Transaction is following
+        | Action        | Package                                   |
+        | reinstall       | flac-0:1.3.3-2.fc29.x86_64              |
+   When I execute dnf with args "repoquery --installed flac --qf='%{{name}} %{{from_repo}}'"
+   Then the exit code is 0
