我在库中有一个 DbContext 以及实体及其在 fluent api 中的配置。
我在两个不同的项目中使用相同的上下文。第一个是测试项目，第二个是简单的控制台应用程序。
我执行一个查询，包括它的一些关系，如下所示：
var vacancies = (from v in ctx.Vacancies
.Include("Categories")
.Include("Levels")
.Include("Contracts")
.Include("JobTypes"));
奇怪的是，控制台应用程序运行良好，但是单元测试突然开始在错误的表中查找。
当我查看它们时，这两个应用程序都会产生非常不同的查询。
我正在使用 EF5 自动取款机，我已经坚持了几天了，对可能导致此问题的原因一无所知。
编辑：关键是我没有做任何不同的查询，我也只有上下文，只有一个我在运行时确认的连接字符串连接到正确的数据库。
我只能说，我觉得流利的 api 在单元测试中没有任何影响，即使它像它应该的那样很好地命中了代码。
public class SchedulerContext : BaseContext<SchedulerContext>{
public DbSet<Click> Clicks { get; set; }
public DbSet<Category> Categories { get; set; }
public DbSet<ContractType> Contracts { get; set; }
public DbSet<JobType> JobTypes { get; set; }
public DbSet<Level> Levels { get; set; }
public DbSet<ExternalMapping> ExternalMappings { get; set; }
public DbSet<GeoName> GeoNames { get; set; }
public DbSet<GeoAlternateName> GeoAlternateNames { get; set; }
public DbSet<Trigger> JobTriggers { get; set; }
public DbSet<RegistryValue> RegistryValues { get; set; }
public DbSet<JobResult> JobResults { get; set; }
public DbSet<JobInfo> JobInfo { get; set; }
public DbSet<JobError> JobErrors { get; set; }
public DbSet<JobNotification> JobNotifications { get; set; }
public DbSet<Company> Customers { get; set; }
public DbSet<Vacancy> Vacancies { get; set; }
public SchedulerContext() {
//this.Configuration.ProxyCreationEnabled = false;
//this.Configuration.LazyLoadingEnabled = false;
}
protected override void OnModelCreating(DbModelBuilder modelBuilder) {
modelBuilder.Configurations.Add(new VacancyEntityTypeConfiguration());
base.OnModelCreating(modelBuilder);
}
}
这就是我的背景。
还有我的实体配置：
public class VacancyEntityTypeConfiguration : EntityTypeConfiguration<Vacancy> {
public VacancyEntityTypeConfiguration() {
this.HasMany(c => c.Levels).
WithMany().
Map(
m => {
m.ToTable("VacancyLevels");
});
this.HasMany(c => c.Categories).
WithMany().
Map(
m => {
m.ToTable("VacancyCategories");
});
this.HasMany(c => c.Contracts).
WithMany().
Map(
m => {
m.ToTable("VacancyContractTypes");
});
this.HasMany(c => c.Jobtypes).
WithMany().
Map(
m => {
m.ToTable("VacancyJobTypes");
});
}
}
以及显示问题的确切方法。
public List<Vacancy> GetVacanciesForCustomer(Company customer, bool onlineInclusive) {
using (var ctx = new JHSchedulerContext.SchedulerContext()) {
var vacancies = (from v in ctx.Vacancies.Include("Categories").Include("Levels").Include("Contracts").Include("JobTypes") where v.SourceSite == customer.SourceSite && (v.Online || onlineInclusive == false) select v).ToList();
return vacancies.ToList();
}
}
和空缺班：
public class Vacancy {
public Vacancy()
{
this.Language = "";
}

}
}
就与数据库的连接而言，您只需要相信我已经检查过两者都连接到同一个数据库。（我什至生成了一个启用迁移的新数据库，因为我们使用另一个上下文进行迁移。那仍然有完全相同的问题）。
澄清一下：单元测试查找表：CategoryVacancys。我使用控制台应用程序甚至我的 Windows 服务来查找正确的表：VacancyCategories。
