242
Since all conflict objects are created with specific semantics for their
243
attributes, each class should implement the necessary functions and
244
attributes described below.
246
Each class should define the scenarios that create the expected (single)
249
Each scenario describes:
250
* how to create 'base' tree (and revision)
251
* how to create 'left' tree (and revision, parent rev 'base')
252
* how to create 'right' tree (and revision, parent rev 'base')
253
* how to check that changes in 'base'->'left' have been taken
254
* how to check that changes in 'base'->'right' have been taken
256
From each base scenario, we generate two concrete scenarios where:
257
* this=left, other=right
258
* this=right, other=left
260
Then the test case verifies each concrete scenario by:
261
* creating a branch containing the 'base', 'this' and 'other' revisions
262
* creating a working tree for the 'this' revision
263
* performing the merge of 'other' into 'this'
264
* verifying the expected conflict was generated
265
* resolving with --take-this or --take-other, and running the corresponding
266
checks (for either 'base'->'this', or 'base'->'other')
268
:cvar _conflict_type: The expected class of the generated conflict.
270
:cvar _assert_conflict: A method receiving the working tree and the
271
conflict object and checking its attributes.
273
:cvar _base_actions: The branchbuilder actions to create the 'base'
276
:cvar _this: The dict related to 'base' -> 'this'. It contains at least:
277
* 'actions': The branchbuilder actions to create the 'this'
279
* 'check': how to check the changes after resolution with --take-this.
281
:cvar _other: The dict related to 'base' -> 'other'. It contains at least:
282
* 'actions': The branchbuilder actions to create the 'other'
284
* 'check': how to check the changes after resolution with --take-other.
223
The aim is to define scenarios in daughter classes (one for each conflict
224
type) that create a single conflict object when one branch is merged in
225
another (and vice versa). Each class can define as many scenarios as
226
needed. Each scenario should define a couple of actions that will be
227
swapped to define the sibling scenarios.
229
From there, both resolutions are tested (--take-this and --take-other).
231
Each conflict type use its attributes in a specific way, so each class
232
should define a specific _assert_conflict method.
234
Since the resolution change the working tree state, each action should
235
define an associated check.

* left_name and right_name are the scenario names that will be combined
307
* left_dict and right_dict are the attributes specific to each half of
308
the scenario. They should include at least 'actions' and 'check' and
309
will be available as '_this' and '_other' test instance attributes.
311
Daughters classes are free to add their specific attributes as they see
